Model: Chevy II
Engine Size: 194
Refrigerant Type: r12
I am working on an old original ac system on a 63 Chevy II and the fan motor isnt working on high due to what I think is the inline fuse.
There is a wire that runs from the relay on the evaporator through the firewall and down to the starter. It has an inline fuse that was blown.
The fuse that was in that read "KILLARC SFE 20" so I thought replacing with "BUSS AGC 20A/32V" fuse would work and it did for a second. Then the high speed cut off and I went to check the fuse and it was blown.
I checked the shop manual and it doesnt say what fuse type to use. There is a wiring diagram that shows from the relay a "12 Gray" wire and it points to a fuse but doesnt say what type/size fuse.
Im thinking that either the previous owner put the wrong in fuse that I copied, or there is a wiring problem that may be beyond me to figure out.
I have a multimeter and know how check a few things with it but Im in over my head on this as usual.
Any idea on how to find out which fuse should I be using?
Probably a 30 amp fuse. Those fusholders used to get hot and burn up. A 30 amp resetable circuit breaker will also work.
