You've got too much load for the wiring. The fan pulls a fair bit of power,
especially when it turns on. You either have to have thicker wire or
separate it as you said off the solenoid. The stereo should have a separate
fuse as it pulls much less current. A relay for the fan would also be the
preferred way. Relay = low power method to control high power device.
My 1960 Mini has only two fuses and NO relays. With hi powered lights I put
in dual relays and fuses. Bosch makes a nice combo relay with a fuse socket
build-in. Real clean install this way.
