I'm investigating various methods of controlling an IC fan (1990 SC w/auto trans) - all include a relay:
I'm leaning towards using #2 & #4.
#4 would make use of a circuit board that would sense idle voltage and rising limit so that the fan would stay on for a bit after being triggered, to help avoid abrupt on/off/on while creeping along in traffic.
Anyone see any liabilities w/#4, or have suggestions for other methods, thanks.
- Run full-time w/key on
- Switched: on/off
- Triggered via main radiator cooling fan (hi or lo?)
- Triggered via MAF voltage so that it runs at idle
