Starting problem

Post by SuperRedMR2 »

right,

ive changed the starter motor now and i still have problems getting the car to start. the battery is fine as ive measured the voltage and stuff etc.

this morning i turned the key...nothing...just a clicking noise i can assume is the starter motor. then after leaving the key turned it began to slowly come to life. feels like when your alternator is not charging the battery and you get the slow burst into life...but not...!

are they any relays or fuses to check? ive just cleaned my earthing points up, all except the starter motor, which i should have done at the weekend but forgot.

any ideas?

Still sounds like a battery prob to me...are you getting 14.4v across the battery on standby? What voltage do you get when its cranking over? Have you tried jump starting it to see if it goes?

oh yeah it cranks. its intermittant.

it works by push starting it in really desperate situations.

the battery was at 14.4 with the engine on and cant remember what it was when it was off.

Turn the heater fan on in the car before starting, when cranking, does the fan slow right down?

If not then the problem is not a bad battery, more likely a bad starter motor :(

Measuring the voltage wont tell you much at all, you need a drop test done on the battery. If it starts with a jump pack/jump leads then its your battery.

I have changed the starter motor and I tested it before I put it in.

The battery is two years old but I thought it would have lasted longer than that.
