dmoore 1,036 #102 Posted August 18, 2022 Hood should be done this weekend. Share this post Link to post Share on other sites
dmoore 1,036 #104 Posted August 30, 2022 (edited) Mounted the hood and made a few adjustments today. I'm really happy how this little tractor came out. Had some noise initially coming from the brake pad. Removed it and the noise went away so I guess I will sand down a little of the top portion of the lining. You can see the dark spot where it was hitting without applying the brake. Thanks to all who helped out along the way and I hope this restoration will help someone in the future. A special thanks to Terry for his fabulous decals! Edited August 31, 2022 by dmoore Share this post Link to post Share on other sites

On the four tractors I've refurbished, all had plenty of lining but it was glazed or weathered and looked iffy to me. As you are planning, I did a bit of sanding with a medium grit flap drum to take off the glaze or weathered material and they all work great. Share this post Link to post Share on other sites
dmoore 1,036 #108 Posted September 1, 2022 Removed the brake band and sanded off a little material at the top. re-installed, no more noise. Share this post Link to post Share on other sites
dmoore 1,036 #109 Posted September 1, 2022 Question, for those of you who have the older starter/generator setup what should the generator output be at idle or any speed? I'm only getting battery voltage 12.3 volts. Share this post Link to post Share on other sites
rjg854 13,199 #110 Posted September 1, 2022 Not that the Ammeter is that accurate, but at idle my 854 shows in the negative. At full throttle I think it should be putting out between 13 and 14 amps. Share this post Link to post Share on other sites

I'm only getting battery voltage 12.3 volts. I have both ammeter and voltmeter and no powered accessories. At low idle: 12.1v (battery voltage), negative amps (2-3) (generator has not reached the regulator's minimum threshold voltage so engine is running on battery-powered spark) At medium idle to full throttle: 12-15.5v, positive amps (2-3) if still charging battery from startup but zero amps after three or four minutes of runtime when battery has reached full charge. The "stock wired" ammeter measures ONLY the current going into (or out of) the battery, NOT any current from the generator being used by other powered accessories. If you have correct wiring, and a properly functioning regulator, the tractor and battery will see as much as 15+ volts with engine at 3,000 RPM. The S/G actually puts out a voltage directly proportional to its rotational speed that is well above 15v, but a properly adjusted regulator won't "pass through" any voltage less than 13 and "chops" high voltages down to an effective voltage of 15+. Using a sensitive digital voltmeter on the regulator output can be ineffective due to the rapid "on/off" of current coming from the regulator. An analog meter is more useful.

dmoore 1,036 #112 Posted November 4, 2024 Wow! didn't realize this thread was over 2 years ago....I never went back and investigated why my ammeter didn't show a charge. However, I did read a thread here a while back about making sure the generator mounting was free of paint and making a good contact to ground. I will bet this is my issue. Everything got painted back then. Share this post Link to post Share on other sites
dmoore 1,036 #113 Posted 23 hours ago Well it's almost 2 years later and I finally got back on the no charge issue. Thinking it was paint that was not making a good ground I removed the brackets and scuffed the mounting points and put it back together, still no charge. This is a new regulator I purchased back when I restored the tractor. With a jumper wire I jumped between the field terminal and ground and the ammeter jumped to the right. So I guess the generator itself is working. I wonder what's next? Share this post Link to post Share on other sites
Handy Don 16,970 #114 Posted 2 hours ago Being a bit OCD myself about some things, I’d go through with my ohmmeter and confirm to my own satisfaction that there really is no resistance where there shouldn’t be. Consult your tractor’s wiring diagram. I had (and still have on the shelf) a “new” regulator that really didn’t do the job and it wasn’t adjustable. Found an old adjustable version, cleaned it’s relay contacts carefully and gradually was able to adjust it to correct operation (the adjustment were as little as a few degrees on the screw). I put the blame squarely on @Achto for getting me to dig into S/G and regulator details and, for me, it was a revelation (I hereby acknowledge a degree of fascination with these electromechanical devices). There are a number of steps for checking out regulators too involved for a simple post--sorry. Wading through this document can help. WH regulators are the “two relay” voltage and current only style. 1 Share this post Link to post Share on other sites

Never trust simple resistance readings, load test everything with a light bulb. A good 0 gauge cable and a single good strand of 12ga AGW wire have the same resistance value. Only one will carry a current. Share this post Link to post Share on other sites
