charging question

Postby Jack » Wed May 02, 2018 3:34 pm

hello, I have a charging problem, I went to get the cub out of the barn, and I had to charge the battery it was dead. after charging it up I pulled it out and noticed the my gage was reading on the Dead side, so I cleaned up all the connections on the Battery and voltage reg. made sure the ground plate was clean, then I re-polarized the gen and reg. and still wasn't charging, so I bought a new voltage regulator, I installed it, polarized it, started the cub up, the gage was jumping around on the charge side, I let it run for a short while and when I went back over to look, the gage was reading on the dead side again. when I turned the headlights on the gage went to the low side of dead, any Ideas ? should I remove the tank and clean-up the connections on the generator? and how do I test the gen. to see if it is working?
thank you
Jack

Where did you get it? It could still be your problem.

What is the low side of dead? To the discharge side?

Where in the chart did you have problems? Step 3 or step 4 and what exactly did you do at those steps? The flow chart is useful but assumes some understanding of what to do at each step and each step has to be done correctly. Unless each step is done exactly correct it may give erroneous results.

My experience is that a voltage regulator rarely needs anything except cleaning of the points. The points open and close at about the same rate as a single cylinder engine ignition points with about the same current so the points to need cleaning once in a while. I removed a bad voltage regulator from a cub cadet yesterday since it was not charging. I opened the case and dumped a few tablespoons of water on my bench. Soaked overnight in Evaporust and cleaned the points this morning. Working well. Unless the coils are burned or the rubber mounts are broken then the regulator can be salvaged. I would look hard for another cause before condemning the new regulator.

I only use the USA made regulators, I have found the imports are junk and if they did work they do not last long, USA should have it stamped on it, make sure you have the wires hooked up correctly and good grounds, clean the mounting surfaces and bolts that fasten it

I got the regulator from yesterdays tractors, I am going to start the over with that diagram, and make sure I'm doing everything correctly step by step, and go from there. also I am going to clean the points in the regulator, I will try anything and hope I don't need a new generator.it was fine when I pulled it in the barn
thanks Jack

I went out this morning and did the test on the charging system accordingly to the chart and the photos in the how to forum. After doing the test i started the tractor and the gage was showing on the charge side, but after a minute or two , the gage was reading on the D side.
I am stumped
The regulated is new

Is it a digital meter? They don't like the old 6V systems. Need one with a needle on it.

Only the generator needs to be polarized and only when regulator is disconnected. Regulators are not to polarized, some are for positive ground and some for negative ground, some will run either way. Some will polarize gen at the regulator by jumping battery to gen terminal without unhooking wires, you can do this but it's always safer to unhook wires at regular or generator. Flash battery to arm. Arm and gen safe the same.

Hi,
Welcome to the website Normanott.

Below is a page from the late 1955 Cub owner's manual telling how to polarize the 6 volt system, with voltage regulator, on the right side of the page.
