hard starting

53 super H · Oct 30, 2010

Installed new 2-00 cables,new battery, had starter rebuilt and starter shop finally gave me a loaner starter that finally works. No one can seem to figure out why my starter with new drive and everything doesn't work when the loaner does. Any ideas other than it might just need a 12 V.
Would like to keep the old Super H as near stock as possible but it is trying me on this one.

If the loaner starter works then I would think there is an issue in your starter. Find a different rebuilder.

Starters are difficult to diagnose on the bench. The heavy windings cause such low resistances that a shorted field, or armature (internal short) is tough to find, though not impossible. If it has new bushings, the commutator trued and new brushes, My guess it is internally shorted.
Testing it on the tractor with a cheap starter draw meter (held against the cable while cranking) and comparing that amp number with the working starter is the best method for making a determination of its worth. Fixing it might be swapping parts in it from the good one till it works, then getting that part new. Jim

I am not familiar with the Super H starter, but when I converted my SuperMTA over to 12 volt I also had the starter converted to use a push button on the dash. I didn't want to loose the screws that held the starter switch on the starter before so put them backin. Starter wouldn't work. Found out that when I put the screws in without the switch they went in too far and grounded the windings.Any chance the screws you have are too long?

The old starter will start the tractor but turns really slow.

I would locate a new shop that repairs generators, starters and alternators. Have them to take a look at your starter. You should try and measure the battery voltage when you are try to start the tractor to see how far the voltage drops. Too much voltage drop doesn't leave much for your ignition. Hal

I have a super H, and use 1 gauge battery cables. I have heard that cables have a lot to do with cranking speed. Although to me it sounds like something is wrong with the old starter.

After 15 seconds of cranking (pull the coil wire first), check ALL conncections having to do with the large gauge cables. If any are warm or hot, that could be your source of trouble, IE, high resistance.

My son found a connection on top of his starter on his C to be an issue to his slow starting issues.

My son had a 6 volt starter that came with a Model A Farmall. It would barely turn the engine over. Jump with 12 volts & it worked ok.
So I took it to our local starter repair facility where they turned the commutator, checked the field coils, and put a bushing in the rear cover. No difference!
I helped re-test the starter at his shop and swapped parts with a known good starter. The problem was that the armature that had tested ok on the growler had some internal open or shorted windings that prevented normal operation and hadn't shown up during testing.
Replaced the armature and 6 volts starts the tractor like a charm!!
Remember: 6 volts was the norm for many years and performs great when the cables AND starter parts are in decent shape.

2GA is probably too small for 6v. I use 0GA and 1GA for all of my 6v stuff, and be sure your grounds are good, and clean. My 6v H wings over just about as qucik as my 12v M does.
