turning over slow, but battery fully charged

[kinkyaz]

hey guys I noticed the other day the car was turning over real slow, then it just wasn't at all so i thought battery must be flat because it had been sitting for a couple weeks. Checked battery its fully charged so not im confused. someone mentioned could be fuel pressure regulator but just want some other opinions?

Your battery could be low on water. Have you checked that?

[noddycommodore]

The easiest way to fault the battery is to check the voltage at the battery whilst the car is being cranked over, anything under 10 volts the battery is stuffed. To rule out your starter motor being worn connect another battery into the mix with jumper cables and if it still cranks slow then it's your starter motor / wiring not the battery

checked water its all good, checked voltage when running getting 14.5v so im thinking possible starter motor but any other ideas?

gday mate, i just fixed this very same problem on my vp v8, was the starter motor solenoid, the battery lead to it was loose and the plastic was brittle from the years of heat, so i removed the starter and replaced the solenoid and its good as new now, so check those things on yours, cheers and good luck.

Check the voltage while cranking, not while running. If the above doesn't fix it.

my old vq v8 was the same,really slow to start and if the motor was warm was even worse,changed the solenoid and was good as new after that

hey guys where would ya get a new starter motor solenoid from? is this something supercheap might stock or will i need to go to holden for it? also whats the deal with the voltage while its turning over what am i looking for?

you get a new starter motor for 160bucks at coventrys, dont know if they sell just solinoid, but if it me just replace starter motor
