temporarily ground F terminal to charge 6volt

Postby ToddW » Wed Dec 03, 2014 6:13 pm

First to admit I'm electrically challenged. Have spent $$$ in new regulator a few years ago on my 1960 cub. after polarizing and checking the wire contacts are clean. the regulator will charge a few seconds after repolarizing then quit. I can get it to charge when I temporarily ground F terminal. was wondering if I put a toggle switch by the dash and ground the F terminal thru the toggle switch when I run the tractor, if I can get by until spring? Do not want to keep putting it on trickle charger again during snow pushing season. just grounding the f terminal when running it every few minutes might also charge it I'm thinking

If you do that you will run the risk of over-charging the battery. I suggest you go back over your connections and especially the ground connection of the regulator. Have you had the regulator bench tested to assure it is working right?

Todd, go to the electrical part in the How To Forum. I have some threads there on checking the charging system and one on adjustments to the regulator. The adjustments probably aren't exactly the correct way, but they have worked well for me.

I did have the regulator off today and looked at the points again. the open points were a bit burnt ($75 regulator is 3 years old and was bench tested with my generator when I bought it). took a clean small file and re-dressed the points. When all re-hooked up it charged about a minute then failed again. Then took a temporarily wire from F terminal to a bolt grounding the regulator and it then charges. Logic is telling game the regulator is grounded good because the jump wire is working from that bolt
Mark I will look at the how-to you mentioned an give it a try.
Don't want to buy another regulator right now if I can get by for a few months. Last winter I charged the cub like it was a yuppie electric smart car or something every snowfall and don't want to go that route again.

The normally closed points are on the side where your problem is. The normally open points were working fine. Is the little ground cable on your regulator OK?

What Jim said, I had to resolder mine years ago. Worked fine ever since.

Jim, the grounded wire meaning the copper braided wire on the outside of the regulator?
I will check it closely tomorrow.

Thanks you all for helping to trouble shoot the issue. Think it is indeed the closed set of points that is the issue. filed them more and cleaned them. followed some of Birddogs how to and loosened the tension on the spring holding them shut. Ran tractor with regulator cover off and still no charge. jumped the f terminal again and the closed points opened up.
Took off the jump wire and the closed set of points opened and closed with small spark like it should. It is running and charging for now, have no idea why the f terminal jump started it working again. Maybe the looser tension on the points spring is helping it open and close better?

After any regulator adjustment, replace the cover and check all the operating factors again. The cover can change the operating characteristics of the regulator.

Even with the cover back on the regulator the ammeter needle now shows a slight charge response even when the work light is turned on.
A bit nervous to put the hood back on-that will unleash the charging gremlin living somewhere in this loboy

If you loosened a spring that holds those points shut, you have reduced the voltage that they will open at. The effect of the looser spring is to reduce the voltage where the regulator cuts off. As long as the points are shut, the actual tension on the spring shouldn't make any difference on the ability to charge. Your non-charge situation has to be a poor or non-connection through the 2 contacts of those points. Your jump wire caused the points to cycle open/closed and the physical motion probably improved the electrical connection between the two contacts. I suppose the changed spring tension could have had some odd effect on the closed points but it seems unlikely.
