B-110 starter/generator check?

Recommended Posts

My "new to me" B110.

Put a new ammeter on as old one had broken needle. Does not show charge or discharge when running.

Which terminals should I check with a voltmeter to see if generator is working? Or if the regulator is working or not working?

Thanks.

No, the other probe to ground. The voltage regulator should hold the produced voltage to that level to avoid frying the battery.After checking for 15-16v at the "A" terminal, check the "+" terminal of the battery. It should read the same as you measured at the "A" terminal. If not, then there's an issue in the wiring back to the battery. Could be a blown fuse as shown in one of these wiring diagrams (push button start vs solenoid start):

Also, the battery will only show charge just after starting the tractor when the S/G "replaces" the amps used in starting (assuming a fully charged battery). The S/G will provide current to any accessories directly without the current passing through the ammeter.

Will have to check, hopefully Monday, as weekend is busy with things other than tractors!

Thanks, Bill for all the info.

Will get it figured out - step by step.

      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!😁
