Alternator Field Circuit Breaker Tripping.

[loy53]

Paul,

I had the same problem with the alt field CB tripping .

No. 1 Check all the gound wires

No. 2 I had a loose wire on one of the CB for the alternators.
also while I was trouble shooting the problem I burned up
both regulators.

To solve my problem No. 1 I tightened the loose wire
2 I changed the CB on both alts. & the field CB
also I had to change both reg.
It has been about 20 months ago no problems yet??
hope this helps.

Howard

ps. my 337 is a 1965 model
