So I have a fairly new to me 803. It ran fine a month or 2 ago. Today I went out to load test it and nothing. No pumps or lights kicking on. I took my multimeter to my batteries and one was at like 4v the other was at -2v. The -2v battery reversed polarity. I went out and bought a new battery. When I reconnected the new battery and before I connected the cable that goes to ground I put the meter between the terminal and the cable. It read 0.L.
I’m assuming what happened was I have a short somewhere and it drained the batteries and one was charged in reverse from the other resulting in the polarity swap. I also noticed that the oil fill cap chain was corroded as well where I had it folded on top of the cap.
I’m definitely thinking that I have short somewhere. I checked from the terminal to the case and I have 0.L between the two. Not sure if that’s supposed to happen. ![D396D3E4-485A-43C8-A434-038441C9940E.jpeg D396D3E4-485A-43C8-A434-038441C9940E.jpeg](https://www.steelsoldiers.com/data/attachments/599/599999-6b6c326105c759ec62ad25c6d5b847ae.jpg)
I’ve looked at the battery cables and they are in good condition. No breaks, rubs, or abrasions. I don’t think I had this problem before I moved it. I moved it about 200 miles on the trailer you normally see them on. I’m thinking what during the trip something bumped loose. Also before the trip I disconnect the cables from the lugs and from the transfer switch as I had another generator on the trailer as well.
What I’m looking for are common places to start and check for shorts or someone to tell me I dumb. Thanks for the help!
