P38A Fuse 1 blowing

Hi all,

I have a problem with fuse 1 blowing repeatedly. You have pointed me to some very good articles/threads on here relating to this, and I'm planning on following those steps.

However, I'm hoping I might find a short cut.

Fuse 1 blows shortly after the engine starts - but not when the ignition is on, so I can use window switches, stereo etc without problem, until I start it - then it goes.

Does this help point me in the direction to look at all?

Cheers

Nick

Quick update. Since I had to move the car and I knew it would blow the fuse when I started the engine, I removed a good fuse from Fuse 1.

Started the car and as you would expect - no lights on the instrumental panel.

Then I looked in the stereo bay to check for worn wires etc, accidentally leant on the window switch and down went the front window. All the windows are working from the central switch pack - but there is no fuse 1 in place...

I'm feeling a twilight zone moment - any ideas?

And now the window switches don't work - is there a capacitor or some way that the windows could work without F1 for a few minutes, then stop?

Fixed it! Yay - (doing this thread all by myself).

For anyone interested, in case this happens to you - recently replaced the switch pack - the wiring loom from the switch pack moved about in the bay underneath the pack and became entangled in the hand brake mechanism, leading to two wires becoming chafed and shorting the fuse. Voila!

Has been done before. Lesson to learn is take more care.

It was due to your help and Marty's thread that I sorted it, read it a couple of times, did the Voltage check across the fuse - then thought about the issues mentioned with chafing wires and screws shorting cables, so I thought I'd work backwards from changes that I had made, (The honey mooners on the grassy bank v standing in the boat manoeuvre), and there it was.

Yep just so, i wonder how many people are persuaded to send BECMs away for expensive repair when no repair is required?

Glad you sorted it...our problem it came from another garage who claimed to have checked everything out and Barry used to work for him so had to take his word for it...ours blew the fuse as soon as battery connected...
