Der Diesel is dead

reichouse · 02-06-2005, 11:37 AM

I have a 91 golf diesel, replaced glow plugs, battery
fuse and relay. rlelay light on dash lights and correctly cycles, but no
power to plugs.
Can I rewire the potential bad ground or short in the system without creating another problem.

Thanks,

The glow plug harness shorts out internally on all TDI usually after 60-80k miles. Get a replacement harness from a vw dealer.

This is a pre-TDI auto, It could be a short, but does not have "easily replaced" Harness. Thanks for the reply

I wouldn't suspect a short unless it blows the fuse all the time. There is a bad connection on the power side as the plugs ground in the cylinder head. The relay has two large terminals, one should be 12V + & the other goes to the plugs. Get a jumper wire & connect the two pins on the fusebox to see if you get power to the plugs then.

THANKS FOR THE INSIGHT, THE 50A FUSE ON THE FIREWALL WAS THE PROBLEM
