Recommended Posts

poppie59

1995 520-H  having electrical problems. When I attach continuity tester to frame and then to spade on starter where blue wire attaches the light goes on. I am wondering is the starter grounding out?

Also when I attach tje continuity tester between the frame and pink wires on instruments it is also showing a current. help please thx in advance

It's one of the safety switches, please down load the demystification guide here in the manuals section.

I think that you are using the tester improperly.  There will be continuity thru a solenoid and thru lamps, etc.

lynnmor.  you are correct after  I  read your post I realized the bulb will continue the current thru. My ignorants. I will keep trying to figure this thing out. It all started with the fuse melting at the fuse block. the fuse was the one that the two wires come out,

Good place to start.  Are you getting 12 volts on both sides of the fused circuit?  I have seen corrosion in the fuse block cause a poor connection that heats the fuse.  One source of fuse blocks.

Thank you all for the help. I cleaned almost all the connections and got the tractor started. Ran a separate wire from the neg side of battery to voltage regulator

to help ground the voltage regulator. my last question is my voltage regulator is putting out 18.5 volts to the battery, is this to much voltage ?

Yes it is too much.

Do you have an analog voltmeter you can try?

Sometimes the ignition systems generate too much interference to get an accurate reading with a digital voltmeter.

No I do not have an analog voltmeter. Should I replace this voltage reg?

With the key on but the engine not running compare the Wheel Horse voltmeter to the digital to see if there is a difference. The voltmeter in the dash is analog. If they are close to the same and the dash gauge goes up above 14.5 volts with the engine running I would say replace the regulator.

Thank you Garry I will check when I get home later. I do know that the dash gauge shows over 16. Volts as it is pegging all the way to the right when tractor is running.
