poppie59 1 #1 Posted July 13, 2019 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 Share this post Link to post Share on other sites

lynnmor 6,777 #5 Posted July 14, 2019 I think that you are using the tester improperly. There will be continuity thru a solenoid and thru lamps, etc. Share this post Link to post Share on other sites
poppie59 1 #6 Posted July 14, 2019 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, Share this post Link to post Share on other sites

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.

poppie59 1 #8 Posted July 19, 2019 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 ?

gwest_ca-(File Mod) 10,498 #9 Posted July 19, 2019 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. Garry Share this post Link to post Share on other sites
poppie59 1 #10 Posted July 19, 2019 No I do not have an analog voltmeter. Should I replace this voltage reg? Share this post Link to post Share on other sites
gwest_ca-(File Mod) 10,498 #11 Posted July 19, 2019 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.

poppie59 1 #12 Posted July 19, 2019 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. Share this post Link to post Share on other sites
poppie59 1 #13 Posted July 31, 2019 Thank you all for your help. It turn out to be a bad voltage regulator. Replaced and running again. Share this post Link to post Share on other sites
