Hi,

Whats the normal fuse on the standerd heater in a 1988 mini?
And which one is it in the fuse box?


Ive just bought a new heater and want to use the origional wireing if posible.


Thanks

It's fuse 3 which is a 25 amp glass cartrige (giving the circuit a 12 amp continuous load maximum - if the new heater is designed to use a blade fuse the rating quoted for it in the instructions will be the continuous rating not the blow rating). Bear in mind this circuit also runs the wipers and washers and the radio as standard so all of that current isn't available for the heater. The wiper motor is 14 watts running so assume the heater is allowed 10 amps. The standard heater probably runs at 5 or 8 amps.

Ok, thanks

This new one comes with an inline 15amp glass fuse, the instructions are in french for some reason , but the wireing diagram is pretty simple.

If the current circuit cant take it then ill find a new feed.


Thanks

If it comes with a 15 amp glass fuse that implies it draws less than 7.5 amps running. I'd say that it will be fine to be honest.

Although having said that, if the wiring in it is designed to be fused at 15 amps and you fit it to a circuit fused at 25 it won't have adequate protection. Fitting two fuses in line with each other is bad practice, but you can justify it.

I'll run a new live feed for it, its no extra hasstle, and far safer i think.
