Slow cranks and battery gets drained in a couple of attempts
Hi all,
I am having starting problems on my T25 1.9L petrol.
Generally starts off well but randomly does this thing where it cranks really slow. After a couple or max 3 attempts my battery gets completely drained off and the battery leads turn really hot. I have had to call breakdown around 4 times now to get it jump started. One of the breakdown technicians suggested I check the earth from the engine. Any suggestions on what could be going wrong and where do I start to get this troubleshooted.
Thanks,
Desmond.

Three areas to check.
Firstly thoroughly clean and properly tighten both starter battery terminals.
Next remove earth wire from gearbox mount. Thoroughly clean and refit.
Lastly, remove starter motor. Clean the area where the starter sits against bell housing.
There are other checks...oil lite bush in bell housing. Ignition switch. Voltage drop in starter cable etc etc

Could also be the olite bushing jamming the starter ……

Hi,
Have been looking to clean the earthing points due to an electric fault and found this wire hanging loose in the engine bay.
Any suggestions on what wire is this?
Thanks!

Not sure what the connection is but you look as if you have a few vacuum pipes missing from the air box, unless it has been modified.

The plug is a defunct VW factory diagnostic plug.
