loosing charge while off

Postby inairam » Sun Jul 18, 2021 4:06 pm

I have a round-nose Loboy that has been a great runner. I put a new battery, ground cable and pull starter switch in last year. It has been a great stater ever since I got it.

Lately the battery is always dead. I put my battery tester and it was ready well over 7 volts when running. It starts great with a jump and will start after the battery has been charged from running.

I put a multimeter on the battery when it was off and the battery is losing 0.01 of a volt every few seconds.

I do not see any damaged wires and the lights were off. I thought maybe a stuck regulator? I guessed if it was short it would drain faster than 0.01v a second.

Any suggestions?

I’d still consider the regulator, disconnect the Bat. Wire from the regulator and see if the battery still drains.

I replaced the regulator and the discharge problem went away.

Has anyone seen this regulator on the cub? The armature connection is under the box.

so this may be from the factory. 65-year-old 6 volt regulator.

yup, I do see them once in a while, or could have been replaced at some point with a new delco unit

Hi,
When using that style voltage regulator, the 4 wires are not seen, and like Tim said, the wires stay out of the rain too.

Below is a page from the 1957 Cub operator's manual showing the regulator on the right side.

Below is the wiring page from the same manual, the regulator is at the upper right of the page.
The 3 posts on the side are originally turned facing in, under the hood.

Cubs I have seen had that style regulator too. :)

Mine seems to do the same thing but I've converted it to 12V so not using the regulator.

It was a very neat appearance.

Since it was working I may clean it up and see if it still discharges a battery. The rust between the Battery and the Field terminal may be the issue causing a path to ground through the resister which would explain the slow discharge.
