L48 starting trouble

[CTS]

I am going to throw this out there as it has been stumping us here. We have an L48 (older) that wont turn over with a key. It will start right up when we jump the starter. Once its ran for a bit we can turn it off and restart it with the key just fine. Once we let it sit for some time we have to jump the starter again. We have replaced the ignition and the battery. We are leaning towards replacing the starter relay? Any thoughts? Thanks.

Do you mean you are using another battery to jump start it, or just connecting a wire from the main battery feed wire on the starter to the solenoid on the starter?

Just jumping (hot wire) the starter. some use a screw driver, but we use a jumper wire

Most likely a safety switch or OPC. You have a wiring diagram for it? If you have take a decent sharp image of it and post it.

Could be the starter relay, or safety switch/controller.
I would shoot for the starter relay first.

Do some troubleshooting before you start throwing parts at it.

Does this machine have seat switches, pto switches, clutch switches, etc in the starter circuit? if it does, make sure those switches are operating properly. make sure the battery ground is making good contatct with the chasis. Are battery termnals clean and the battery cables not internally corroded?

We are thinking if it was battery cable issues we could not start it via arcing the starter solenoid??? That's how we know that wiring is good. The safety switches could be an issue, except once the machine has ran some everything works as it should. We can start it with the keyed ignition. It's like a capacitor needs to charge up?? But no ignition cold start. Only jumping the starter.

Lol, I have ordered the full service manual. It should have wiring diagram and I will photo for you.
