620 died

Recommended Posts

My 620 started right up as usual and ran about 20 feet and coughed and quit. Now It will not turn over, fuel pump runs but nothing to starter. Hate wiring so really don't know where to begin. I fooled with a couple wires but nothing there all safety switches are bypassed. Maybe just call Steve at B&B in Jersey and get new harness what ya all think?

Hi Lloyd, I go through that from time to time. I start at the ignition switch, then battery h2o, then charge.

Last time, had a bad connection in the switch plug, low h2o. Charged it, only to find it was a bad battery. I had replaced it 2yrs 9months ago @ Costco. Had a 3 yr warranty! Replaced & no worries.

Also check the PTO switches. I have had to clean them from time to time. I think they are in the power circuit.

Thanks JP, new battery last fall when I put external alt on, new switches on PTO Every thing but wiring harness was new when I rebuilt tractor. Son inlaw is coming down today to look at it, he's real good at electrical stuff me I kind of suck when it comes to electrical, can fix anything else just not that.

Hey Lloyd could it be the circuit breaker? Was your ignition switch new? I had this same problem with one of my powermaxs I ended up running a new wire from the key switch to the starter, some where along the line the little wire from key to the starter must have broke, I took a tester and figured out what pole on the key switch lit up when I turned the key and ran a new one right to the starter and it hasn't failed since. If you have any questions feel free to give me a call

Hey guys son inlaw found the problem, seems the wiring harness got between hydro lever and frame work and cut two wires one being power to starter. So after about 2 hrs. and a lot of testing we're up and running again

      Good morning peeps! I’m always searching for helpful information with my AC collection. Hope to find out new information and pass on my own experience in restoration. Here are some pics of my babies. I’m still looking for front rims for the 410 so yesterday I put the 310 wheels on took it for a drive. Working pretty good but still needs some carb work. Gotta get the 310 running next. Have a great day!😁
