Charging question

Postby noisyone » Fri Sep 14, 2018 3:21 pm

My 1968 Cub Lo boy dies as soon as the battery is disconnected. Would the voltage regulator be the most likely candidate for this problem or would it be something else in the charging system?

It's not designed to run without a battery. Not only won't it run but disconnecting the battery can result in voltage spikes that damage components.

If you're chasing a charging issue step 1 is always connect a known good, fully charged battery.
