A voltage??

Postby Dusty B » Sat May 08, 2021 4:54 pm

Does the A have a 12 V system normally?? Have a 48 A, New 6 V battery will not crank over at all even with direct leads to the main lug of the starter and direct ground to the starter bolt! With a 12 V battery quips over with good speed! Does that mean that the starter is a 12 V starter or does the starter have a problem? Can’t say going to the expense of rebuilding a starter if it operates on 12 V. Will using 12 V for the starter and convert rest of the system to 12 V have any effect considering that it is operating off of a magneto? Am I correct in assuming that the magneto and ignition system operates completely independent of the rest of the electrical system? Going to have to do a complete re-wiring of all accessories anyway! :lost: :help:

Yes! Magneto is independent of the battery system! :)

Most likely weak 6 volt starter.

If your up to it you can usually clean up the comutator, new brushes, bushing, and bearing for around $20- May be more since I haven't priced the parts lately. NAPA or on line for the parts.
I have an excuse. CRS.

The "A" would have been 6 volt, the starter could have been swapped for 12 volt, but it's unlikely. I'd guess that the starter need attention. Get the parts, Eugene mentioned, and bring it to the Bash, I'll take a look at it.

May stick it in Gary, or just run it on 12 V! Will see how things go- just want to crank it over fast enough to do a compression check! Rick rebuilt the mag so my understanding is that I can go either way on the rest of the system!??? Can buy a new 12 V alternator for less than it would cost to repair the generator! If engine is decent it will become my work tractor for pull implements! The B just comes up a little short on an 8’ tandem disc! Especially in plowed ground!

The thing is, if your starter is ailing, 12 volts may finish it off.

DUSTY!!!! Wot the heck ya up to now, ole buddy???? --- Gittin any farmin done! lol! ---- only had 3" of rain here Saturday night! No garden for a while now!
Straight A would have been 6-v, but most get 12-v hooked to them---- sounds like your starter has gone south anyway so 12-v now aint gonna make it any worse. Mine started fine on 6 when it ran so your starter is the problem.
I prefer 12-v whenever possible just for the fact that all sprayer pumps and other stuff is 12-v so with 6-v you are limited to use.--- just what I have learned! lol!
8' in plowed ground??? time for squadron hitch!!! LOL!!
