another starter issue

Postby wgriffin » Fri Jul 05, 2019 2:38 pm

Having fits from my YM2000. I overworked it and blew the head out in the woods, then seemed to have cooked the starter. My fault - installed a new head and a new gear driven starter, all parts from Hoye of course. But now the starter is still a problem.
Installed the Chinese made gear driven starter, at first it started right up. Then soon it would not. Nothing, no clicks or anything. Turns out that apparently it was a loose wire somewhere. After going over that, including double checking the ground, got nothing at first. Then it started just fine for several starts.
Then it would not start again. I pulled the starter and took both the gear driven and the original to an auto parts store to have them tested. The guy there said the old one was good - he hooked it up and it did like it should - but the gear driven one was "no good". So I re-installed the old starter, and a new battery to starter cable, still nothing.
Laying a screwdriver across the hot terminal to the spade terminal (called terminal A to B in your starter testing article) gives me nothing but a click. This is more than I got with the gear driven one. Jumping from A to C gives less than that.
Turning the ignition I get a click and no more.
My headlights can't be used for help in diagnosis. They haven't worked in years so I have them unplugged anyway.

Have you pulled the battery ground cable off at the frame and cleaned the connection?

thanks, Winston. I re-tried that just now. No change.

It sounds like the engagement gear is pushing out, but the starter is not turning over. This is with the old starter re-installed.
(When I turn the key, I hear a clear "tank" sound from the starter, no more)

Battery tests at 12.8 volts
Laying an old screwdriver across the starter's battery terminal to the control (?) terminal (A to B per Hoye's article) doesn't give me much more than sparks. Once the starter almost turned over. I am not sure I can get a good connection with just a screwdriver anyway.

Could try a remote such as this. https://www.harborfreight.com/search?q= ... r%20switch
"If" the auto parts store test was good then you evidently have an issue elsewhere. Most times it is a bad connection, sometimes bad cable, sometimes switch, etc. Using a remote or even a screwdriver should bypass the switch eliminating that as a problem.

Might try one of those remotes. We have a harbor fright nearby.
Pretty sure the starter is no good. Tests indicate that it is getting 12V or so, just not turning over.
I don't have much faith in the tests in the auto parts stores. They require a make/model etc of car to run their tests. Not having any instructions for a YM2000, they just guessed close as they could. Although one guy did get the original starter to run on his test machine.

I can tell you with bad connections voltage readings can be confusing. Might try watching your readings while engaging the starter. Might want to consider attaching jumper cable ground to a good grounding spot, then touch hot jumper cable to starter and see what happens.

Sounds almost like something you need to say "hey ya'll watch this" or "hold my beer" before I do it. Seriously I see what you are suggesting, though, and I tried it. I used my battery charger, first set to charge then to start. I grounded it on a head bolt. Touching the hot clamp to the 3 terminals, I got nothing on the 2 larger terminals (battery and starter motor terminals) but a spark. I got the sound of the drive gear pushing out and retracting when I touched it to the ignition terminal.
Almost convinced both starters are no good.
