Fuses

[chiltern5]

I have just bought a +2s130 1973 and the fuse panel on the dash has 4 fuses in it the left hand one (passenger side) keeps blowing but I cannot find what it controls, any ideas.

Looking at the wiring diagram in back of workshop manual, its for the following:
Cigar lighter, clock, map light, horn relay, boot light, glove box lamp, door warning lamps, interior lamps, interior panel light switch & panel (instrument) lights ! Aren't you just glad you asked ? Rgds J.

Thanks looks like it's going to keep me busy for a while. I know the clock does not work so might start there.

put a nail in the fuse and replace what burns-----[-dont use a 22 cartridge] edlaw

Ignore the previous advice, it may be the car you replace!

A matter of trying different circuits after the fuse is blown or pull it and seeing what doesn't work. The wiring diagram will help, you'll be able to see what components are on the same fuse.

Sounds like you've got a dead short. You'll need to isolate it and correct the component or wiring.

As per the prior post, the nail is a BAD idea. Most likely will cause either the faulty component or some length of wiring to catch fire or at least get nice and hot and cause smoke to fill the air. You'll find the faulty circuit faster!!! But, the likelihood of collateral damage is too great.

start with your horn push as it is the easiest, it uses a ring of copper set at the top of the column, and a sprung pair of contacts inside the back of the steering wheel boss. I had a repeated fuse blow a couple of months ago, and one of the sprung contacts had got scrunched up and was pressing on the column causing the short.
