6 volt slow turnover
Hello Everyone,
I hope that you are off to a great 2017. I'm looking forward to a great year and plan to put in my 1/4 acre garden this year, so I'm trying to get my Cub all tuned up for the season.
The problem I'm having is my starter turns the engine very, very slowly and barely cranks. I got my generator checked out and the repair shop said that the gen was good but changed my V. Regulator. Initially, I was showing a sight positive charge, but the needle on the Volt Meter jumped around a lot, then after a few days of running the needle is stuck on discharge.
I have a relatively new battery and it tested good, and even when I put a charger on it, the starter seems to crank very slowly, better but slow.
Do I need a stronger battery, one with more cranking amps? Any ideas on what I might have going on, suggestions?
Thanks,
The Riot

Re: 6 volt slow turnover
Try cleaning all terminal connections so they are nice and shinny. Tell us what size the big battery cables and ground cable are and where the ground cable connects to ground. Came from factory with positive ground so tell us if it is wired neg or pos ground.

Re: 6 volt slow turnover
Move the battery ground cable from the battery box to the top of the transmission. While in the auto parts store, purchase a new ground cable.
Try the suggestions above.
Couple other possibilities, starter needs repair and that your newly purchased regulator is faulty.

Re: 6 volt slow turnover
Attach some jumper cables from the battery to the corresponding connections . Negative to the starter switch and positive to body ground. If it turns over faster that may indicate that the cables may have internal corrosion causing a voltage drop

Re: 6 volt slow turnover
a Properly set up 6 volt system will start the cub just fine. Do as other have suggested and clean the connection and move the ground cable. My 1949 had the same issue and it turned out to be the bushings in the starter were binding but check everything else first.
" running the needle is stuck on discharge" Make sure you wired the regulator correctly and clean the connections.

Re: 6 volt slow turnover
Thanks again, everybody. I'm thinking a good clean up of all contact points, ground etc.,will be the first order of business and I like the idea of going direct with jumper cables, but considering what I see it doing I'm betting on the starter brushes. Of course it's probably a combination of things.
It looks like these VRs are pretty temperamental, the one I has is brand new and it surely looks like it's now working properly.
I appreciate all of the expert advice.
I'll post the findings and results ASAP.

Re: 6 volt slow turnover
I like the 6v postitve ground systems if there maintained well. The proper cable size to battery with soldered terminals makes a big difference. If u changed voltage regulator, make sure u polarized it as per owners manual. If u think starter may be weak brillimans sell and overhaul kit with bushings and brushes very reasonable. Good for another 50 years.

Last time I had a generator rebuilt I took the regulator in with it,the shop repaired my generator,bench ran it and adjusted the regulator to suit.

Re: 6 volt slow turnover
As a side note I have found the newer vr's to be not as reliable as they once were. Either the import or US built ones. I had Wiltons auto electric build me two solid state ones probably 8?years ago. Unfortunately the owner passed away. They have never given a bit of trouble and unless u take cover off vr u don't know they have been modified. Clover systems in California make them now but have never tried there's.

Re: 6 volt slow turnover
I agree with Steve the VR available now are not reliable. I have two from Clover and they have worked so far but it has only been a season viewtopic.php?f=1&t=94792

Re: 6 volt slow turnover
I sent a note to Clover Systems to get details about their Solid State VR, I'm very suspicious of the aftermarket mechanical VRs, very poor quality. The first one I got was bad out of the box, the very well known vendor sent me a new one without question and didn't even want the bad one back.
The generator repair shop that checked out my gen did bench test and set my gen with the VR.
I believe I will probably get a rebuild kit for my starter and refurb it. Also, I will post results on the Solid State VR.
Thanks Again to all.

Re: 6 volt slow turnover
Get a timing light and check your timing on the engine, use a 12V external source to power the light. You would be surprised what a little out of adjustment timing will do to a 6V system when cranking.

Re: 6 volt slow turnover
Minor point, but to be technically correct, "it" is the generator, not the regulator, that is being polarized. (Maybe you meant that and just shortened your description a little to much???) The magnetic field in the generator is polarized to the correct orientation by using the easily accessible, and usually better marked, connections on the regulator (which leads to some thinking they are polarizing the regulator). The regulator connections are electrically the same as the locations on the generator, which are usually harder to get to, and the markings are usually painted over and difficult to read. That is as long as it was wired correctly.Stevetractor wrote:....... If u changed voltage regulator, make sure u polarized it as per owners manual. ......

Re: 6 volt slow turnover
Just reading thru this thread for the first time and I didn't see you reporting back about cleaning connections or trying to jump start directly to the starter switch and good body ground.
Lots of good suggestions above. Please let us know which ones you actually did and the results before you start rebuilding or replacing things. This will help us diagnose the issue AND be a good reference for future readers of this thread (to have problem stated, suggested solutions, and problem solved all in same thread). Help us help you.
