​ELECTRICAL PROBLEM 1 

Problem - Fuse no 18 on the main board has blown and there is a short to ground somewhere on this circuit. This fuse serves the central locking, fuel flap, and some element of the electronic ignition. With this fuse gone, the fuel pumps don't cut off at start up, but car runs ok. I have disconnected the motors for the central locking and the fuel flap, but the short to ground is still there. Car is a 1991.

Possibility 1 - The best way to go about this is to pull the fuse, open the fuse box panel, note the wire colors going to it. Switch on the ignition. Find the +12 V pole of the fuse then from the other pole measure resistance to ground. If it is 0 you have a short. Disconnect the same colored wire at fuel pump see if the wire still goes to ground, if not then the other side of the fuel pump etc. Follow the wires as best you can around the car. If it is a transient loose wire rubbing occasionally against the frame it will be a real pain to identify!

What Our Member's Are Saying

"I have spent hours looking for fixes for my Lambo and here it is in one website. Great value for money and very easy to use." Charles Wigins

"Fantastic concept and the information is very well set out. Every model for the one price is brilliant. I fixed my problem by searching another model." Tyler Mendo

"I have recently sold my Countach but I would like to give a big shout out to the one person who has been collating this information for many years and has made this website a winner. Jason is a handicapped man who is the driving force behind this website. I met Jason and his brother by accident at a car event in Australia. Even though he will never drive a car, he sure knows how to drive the internet. Well done Jason and keep up the good work." Mark W
