Doesnt start once hot

[jazz5000]

hasn't given anymore trouble since in the same circumstances. So i hope so 

[jazz5000]

Had same problem again,
So fitted a new battery.
So far so good

I stand correct... haha 

[jazz5000]

Starting to have the same problem again.

Could it be a alternator problem?
As the battery sorted it for a while. So im thinking the battery is not getting charged enough.

However voltage is 14.2v when running etc

hi next time it does it try a pair of jump leads hooked up to another fully charged battery. if it fires straight up then you know the problem aint the starter anyway. is the engine overheating by any chance?

[jazz5000]

Last time it happened I jumped started it and it started straight away .
This is why I changed out the battery.

Don't think car is overheating . sits at 90. Sometimes less .
Happened last time once I did a drive on motorway. Rpms were at 5k so was probably running hot

Temp gauge should sit bang on 90; so sounds like you got a thermostat problem

Also what speed where you doing for your RPM to be sat at 5k??   Or were you driving around in 3rd gear??

[jazz5000]

Went to a garage to do a load test on battery,

They said battery is good.
The alternator is the problem. It is not giving enough voltage to charge up the battery.


Would a 150A alternator go straight in?

[jazz5000]

Fitted a 180A alternator in.

Very happy with the voltage now.

Previously dropped to 11.5v with heater/headlight/rear demister/bass on full/air ride compressor

 

Now it does the above and doesn't go below 13.5v.

Will do the big 3 tomorrow aswell
