« on: 30 April 2009, 19:43 »
i'm having some starting trouble and wondered if i can (using a couple of jump leads) directly connect the battery to the starter motor/solenoid to crank the engine??? :shocked:

Yes

is it as simple as battery (+ve) to starter (+ve), battery (-ve) to starter (-ve) (or earth?).

do i need to connect them up in a certain order?

will jump leads be ok to use?

thanks

What exactly are you trying to do? Are you bench testing the starter - or doing it whilst its on the car?

You just need to clamp the earth to anywhere on the starter casing and clamp the +ve to the +ve terminal on the solenoid. But you'll need to make a short length of wire to run from the +ve terminal on the solenoid to the spade trigger.

while it's in the car, as a means to start the car rather than bump starting :embarassed:

Whats wrong with the existing wiring in the car? Is the starter not turning over at all, or is it weak?

How do you know the battery is ok, how has it been tested?

When you turn the key, do you hear a click or nothing at all? If there is no click, it sounds like the solenoid. There should be a spade connector with a thinnish +ve trigger - make sure it is tight. If it is and still no joy, then use a small piece of wire and short the +ve feed from the battery to the spade, then post back.

That will at least rule out the solenoid / ign switch.

dont think there is any noise usually although sometimes hear the fuel pump prime.

i'll give that a try.

Your saying that it will not turn over, worth checking that the immob. has not stuck in.
