How to test alternator output

Postby RS1301 » Tue May 26, 2020 10:02 am

Every week or so my ranch hand cannot start my 1301D - I charge the battery and it starts right up. I wonder if the alternator isn't charging the battery or is it that the guy isn't giving it enough throttle to charge? Or is it something else...

You should be seeing something over 13v at the battery when the engine is running if it is charging. 99% of the charging problems are a bad regulator
