  1. A lot of good information here. As pointed out check the battery and the connections. I should have said load test the battery as stated. If everything checks out I might suggest that one employ their meter and check the obvious and in my mind that means the safety switches and ignition switch. This is something that can be done easily. I would suggest that you disconnect the battery positive and insure that its away from the positive post. One can check operation thru the various switches by using the ohms position on the meter. Most problems seem to be either battery or condition of connections. Glad to see you found and fixed the problem.

    Z616 park safety switch needed

    Unfortunately neither file is correct. I'll just leave it the way it is. It works and I just need to remember not to touch the ignition switch so I don't engage the starter into the engine that has already been started and running. Thanks for the effort

    Z616 park safety switch needed

    Thank you for the link. Unfortunately the Wheel Horse is older than the oldest Toro model listed. There is no PN on the brake switch assembly on my Z Horse so I would be guessing which switch might work and since they are not available its probably a waste of time to try to push this further. If the whole switch assembly goes south I will purchase an industrial quality micro switch or proximity switch and activate a relay with that. When at the brake position one set of contacts (starter contacts ) are close and the other the ( electro magnetic clutch) contacts are open. When the switch/ brake lever is released the contacts simply go opposite from what they are in the brake mode. Simple to fix. I thought maybe there might be some aftermarket parts available or NOS parts available.
  4. I have an old Z616 Zero Turn that refused to turn over thus requiring some attention. Armed with my VOM meter I set out to see why it wouldn't do anything. Upon a quick inspection I found the parking safety switch to be at fault. This switch looks like a pack of cigarettes with 2 sets of two wires exiting from the bottom of it. One set is for the clutch assembly/blade operation and this set of contacts are open when the parking brake is in the brake position. The other set of contacts when in the brake position allows the starter to operate. The set of wires for the starter operation had broken off the safety switch. The logical quick fix was to connect the start interlock wires together to allow operation of the starter however caution must be employed to make sure that one doesn't accidentally hit the ignition switch when the engine is running. So, what I need is to be pointed toward someone with a safety switch that I can purchase and if they are not available then I will probably just leave the set of contacts normaled together and simply employ extra caution to be sure I don't accidentally touch the starter when the engine is running.
  5. Good point and I'm going to add to it. In addition to using either an adhesive label or wire markers I highly recommend using clear heat shrink tubing over the label marker. This way in 10 years and your tracing something out its a simple matter of wiping off the dust and exposing a label that can be read still.
  6. Good question. The acid fumes are generally associated with battery terminal corrosion. The sealed newer batteries don't have quite the problem as the older batteries with the large cell caps. Having said this there still isn't a battery that is going to be free of corrosion therefore normal maintenance procedures should be followed. In other words preventative maintenance should be used. There is no absolute coating one can use in an attempt to get away from corrosion so the best thing is keep it clean as you would your body and the problem won't come up again.
  7. Actually your post ties in with good connections or cleaning up connections so you can get a good connection. Many times I have seen people with cars that won't crank over and its a simple clean the connections on the battery fix. So, the battery is a really good point to start anytime you have a voltage/current problem. Sometimes connections can look great but remember it only takes a minute or two to verify the connection that you thought was good and was actually the problem.
  8. You might want to be a little more specific when trying to describe your problems. First post should have said something like the engine starts most of the time and when it doesn't start right up it will if I jump the solenoid. This would have hastened up the advice and type of advice given to solve your problem. Just a thought. Soldering components on a circuit boar is childs play. First, use a iron/pencil type soldering iron less than 40 watts to limit damage to circuit boards. Sometimes its easier to snip the component leads next to the component and this allows you to use a pair of needle nose plyers to remove the lead once you have the solder heated up. The best method is to use a desoldering station to heat the solder and remove it completely with the use of a vacuum pump.

    Ignition switch connectors.

    When you purchase quality connectors that fit properly you don't need the click style simply because they fit very tight. In addition to the "Good" connectors I would suggest purchasing the CORRECT crimp tool for those connectors and it is a T&B crimp tool. The T&B crimp tool as its called don't make the typical flat crimp like the cheap tools do. Instead it actually pushes the metal up to really grip the wire. If you look at the tool you can probably see what I'm trying to explain. This particular tool is made by Klein tool and will do a variety of gauges 22-14 and 10-12

    If there is room in the engine shroud you could use a Onan http://www.ebay.com/itm/New-Voltage-Regulator-Rectifier-For-John-Deere-Onan-318-420-P-B-Engine-16-20HP-/391723779094?hash=item5b348e8416:g:57wAAOSw4CFYwPZg At a cost of $12.66 in place of the more expensive unit. Same hookup (2) AC terminals, one B+(12VDC battery) and the chassis ground to the regulator case. If no room simply mount a 12 vdc fan to cool the regulator case.

    You are correct. All current passes thru the ammeter and thus the positive leg. Disconnect the positive and your dead in the water.

    The voltage regulator is more than several diodes and since you cannot take it apart you cannot check it. It contains a few diodes and also regulation that limits the output voltage. My suggestion would be to put it on the bench and feed it AC on the AC terminals, a ground via the case probably, and a battery just like you would have on your tractor. If you happen to have a variac you can easily dial up the AC voltage feeding it and also measure the DC voltage from it as its connected to the battery. If you don't have a variac and happen to have a transformer that is close to the AC that would be supplied from your stator then connect the transformer to the regulators AC input and check the output. Also one might want to make up a cord that has a light bulb in series with the hot leg. Plug the transformer into this cord/receptacle. This will protect the transformer and will light brightly if the regulator is shorted thus saving the transformer you using for test purposes.

    Actually current runs thru the ammeter not voltage.
  14. I would secure a piece of plywood and attach the existing to the plywood. Use long nails to secure wire so you can make the bends and so forth. I think you can grasp the idea. Design the circuit using the notes and observations from other members here that have done re-wiring and are experienced with it. Train yourself to think outside of the box. You do no have to have an out of the box ignition switch for example you can make about anything work if you use your head. Making the loom... With the harness secured to the plywood one can now take measurements and cut wire to the desired lengths. I would suggest a trip to the auto parts store to buy a spool of split loom covering material that the wires can be inserted into. ( Just like the newer cars use a flexible split plastic type covering. This will do several things. One provide a nice looking finished project look and secondly provide protection to the wiring. Please do not use wire nuts or cheap crimp type connectors. The proper the best tool to use would be a K&B crimp tool along with the proper sized crimp connectors and appropriate heat shrink tubing. This is of course my opinions here and may not be shared by others. * Note* I did this when I installed all the aftermarket spark control and ignition upgrades to my supercharged Z-28 LT4 when I had it. When I was done all the wiring looked factory and was neat and tidy.

    Using thick paper gasket for intake?

    I still have a sheet of gasket material that parts stores used to sell and its probably over 40 years old along with a sheet of cork gasket material. These are saved for those special needs that seem to come up once in a while. I generally take a piece of paper and put a very light even coat of grease on the casting and then put the paper over it and then pull off. Once this is done I transfer the paper to the gasket and the grease is transferred to the gasket material and then simply cut the gasket. Or, if you have a can of blue simply spray the casting and press and release the gasket material and the blue will mark the gasket material.
