Picked up a ceramic heater at Pep Boys this am; it plugs into the cig lighter and uses 200 watts. Is this going to be a fuse buster ? Will I have to upgrade the fuse ? Any tips ?

Yes, 200W at 12V is 17 amps. Use at least 14 gauge wire connecting it to the battery, and a 20 amp fuse. Put the fuse close to the battery, not close to the heater. You've only got a 50 amp alternator on the car, so you're using up a substantial amount of available power to run that heater. |
