Help needed with starter problem

[Gazwilly33]

Hi all just wondered if any one could help! I put a new starter motor on my van and it worked fine for a day then come to it the next morning and it started but the starter motor carried on spinning! Even when I turned the engine off and took the key out! Any suggestions on what the problem could be?

Hmmm, very strange indeed, that sounds like a wiring fault somewhere as there shouldn't be any power to the starter without power to the crank signal wire at the ignition...

I would suggest wiring fault too or possible sticking relay

[Gazwilly33]

Where would the relay be? Il try and find it in the morning! Cheers!

Would it be worth changing the the ignition switch?

[paulwhite1987]

Iirc the relay would be on the motor if it has one. Could also be a bad earth or solenoid but they usually result in non starting

[Gazwilly33]

Has any one got a a wiring diagrams for an astra van mk4 please?

Ignition switch. I always advise this to customers when a starter motor is needed. Had problems with switches especially with mk4. As far as I can remember there is no relay. It will not be a bad earth. Make sure no bolt/ nut is on the starter shorting out the exceiter wire to the main k15 wire. Big red one!

I've had them off a couple of times and put back on but seem to be getting the same problem every time!
