Generator Died?

Sun Dec 15, 2013 4:40 pm

Hello everyone! I took my '54 Betty out to clear snow for the first time this year. I was very impressed with the tractor's ability to move even the largest piles...with the exception of whether or not I could get traction on my paved driveway. Anywho - I went to push a mound across our road and stalled in the middle of it. :x :x :x The tractor wouldn't even turn over. Before the town plow came zipping around the corner I managed to tow the Cub back up the driveway with my car. I tested the battery. Dead. I charged it, put it back in the Cub and started her up. The ammeter was just stone dead. No charge. :roll:

Is there a way to test the generator without having to take the entire hood off and trace all of the wiring? :?: I'm not all that interested in trying to use little tools with frozen fingers in 20-something weather if you catch my drift. THANK YOU in advance.

Just a quick thought - with the tractor running or not the ammeter goes negative when I turn the lights on. So that connection seems functional.

Tough to work on Cubs in the winter. The troubleshooting flow chart will help you pin it down. There is a slight chance your generator lost it's 'polarity'.

Plan B would be keep the battery on a charger (preferably a 'smart' one) and that way you can at least use it, be sparing with the lights, they use a lot of power. A Cub will go a pretty long time on a charged battery, the ignition doesn't use much power.

Ah now that's a good chart to keep handy! Sadly, and as some of the fine gentlemen here can attest, I have a horrible electrical system. My cutout appears to be an original item from a Model A. :roll: I removed it and all of the wiring that goes along with it, giving each contact a good cleaning and still no increase in voltage at the battery between running and not. I have a feeling it may have finally "cut out..." :lol: But yes since the tractor starts and runs on a full battery I'm just going to deal with it until spring. I'll throw on the trickle charger when needed. I'm going to pick up a new voltage regulator this week and see if I can wire it properly. I believe a "warm-up" is in order in a few days. We might actually see 40. Just warm enough to be moderately comfortable in the garage. :-:-):

I bet you will find it is the regulator.
