Slow starting when hot

Postby seahaul » Thu Jun 26, 2014 9:32 am

I have two LoBoys, a 154 and a 185. Both of them start and run fine when cold, but after they get warmed up neither will turn over fast enough to start. If I wait until they cool off, they both start fine.
If I connect a "jump box" starter battery, both will start when warm. I've installed new batteries in both but still get the same results.
Can it be that my battery is not strong enough for starting when warm? I'm using a group 26 battery with about 525 amps.

Move the battery ground cable from sheet metal to the top of the transmission.
I have an excuse. CRS.

Be certain you have clean "metal to metal" contact on your ground connection. Paint is not the best conductor.

Yup checkout your ground connection with an ohm meter. A poor ground won't allow the battery to fully charge up too plus the tractor will run poorly on the lower voltage too. My son found the ground is better on the tranny rear cover.

I do plan in running the ground to the engine block next. Then a short wire from the engine block to the frame. And removing the rear ground connections all together. If the 154 is kept outside this rear battery connection on the seat frame can rust. If it's hidden up front out of the weather on the engine it can't rust.

When my youngest son mowed the lawn with the 154 he had a smile ear to ear when he was done.
I'm technically misunderstood at times i guess its been this way my whole life so why should it change now.

My son tried the clean metal on the seat frame and got a 1.3 voltage on the steel. That means the sheet metal is all poorly connected voltage wise.

This ground wire connection could be a big problem on all the hard starting/charging 154's.

Moving the ground wire fixed the problem on both tractors. Thanks for some excellent advise, Eugene. You saved the day again!
