BX Wont crank

[Wull]

If you’re using the 12v constant feed from battery and the battery is good*

*If you have applied power directly to the starter and it doesn’t crank then that’s more than likely the culprit, going on the basis that the starter has a good ground then it should always crank if its in good working order and you’ve applied power direct to it. If it doesn’t then the starter/solenoid is faulty. This method of testing bypasses all safety switches etc, essentially you are bench testing it in situ.

If you are using a separate power supply, like a loose battery or jumper pack etc then you have to apply the negative supply to the frame/starter as well for that to work.

I had two starters last year that were faulty and doing similar except the voltage was dropping to 2v when the key was turned to the start position.

The old dummy fixed it. It turned out to be the battery. It had me stymied because I had placed an ~ 1 month old battery in it several times and only solenoid chatter was the result. Hell one would think that a battery from a 1994 Chevy 350 V8 would turn over a 3-cylinder diesel, it won't. There's nearly 100 cranking amps difference.

Thanks to all for your comments and assists. Gotta go mow.

You really should buy yourself a simple 100 amp carbon pile battery load tester.
They are cheap!
