If you look at your SPAL data sheet, it has a nice little table that shows the different current draws based on the temperature and whether you have it as a pusher or puller. When I shut down my engine, and it is nice and hot, the current draw, as measured, is five amps or so more than when the engine is cool. Of course, the voltage is a little lower too since the alternator is not running. |
I borrowed a friend's amp tool See post #45

Car OFF and cold, with the fan, high beams, and wipers on I got about 15 amps going thru the CB. Seems pretty good to me?
No brake lights, horn or blinkers.
I might have to do this again. It is after midnight and I'm beat. Maybe I screwed this up...LOL
