oneroadkingman 53 #1 Posted August 9, 2018 Not sure this is my first 520 and I've read a lot to stuff with electrical issues I have gone through and clean them up and it was working fine. and then I noticed that now when I turn the key to the start position the voltmeter pins itself all the way to the left like there's a short somewhere. and I do not hear any clicking other the starter so I'm wondering is the voltmeter pinning itself to the left normal ? I'm guessing I probably need to check the starter connections for corrosion but they're is a plastic cap over the end of it and I can't see them it is in a 20 horse Onan thax Share this post Link to post Share on other sites
FatJackDurham 318 #2 Posted August 9, 2018 that's interesting. Sure sounds like it. My voltimeter doesn't work in my 520, so I don't know what the regular behavior should be. Share this post Link to post Share on other sites
gwest_ca-(File Mod) 10,491 #3 Posted August 10, 2018 When it pins to the left is that 0 volts or high volts? Garry Share this post Link to post Share on other sites
oneroadkingman 53 #4 Posted August 10, 2018 that would be zero Share this post Link to post Share on other sites
gwest_ca-(File Mod) 10,491 #5 Posted August 10, 2018 I think that is normal. When you go to START you first get the RUN connection before the START. RUN powers the A (Accessory) terminal on the switch which powers the voltmeter = 12 volts. When you advance to START position the A terminal is dropped = 0 volts until the key returns to RUN = 12 volts Click on the picture and again on the next page to enlarge the switch description.

oneroadkingman 53 #6 Posted August 16, 2018 Well you're absolutely right because that's what it does once it starts it goes back up to 13 volta thax. Share this post Link to post Share on other sites
