Geo Metro Electrical Audit
'97 Geo with 1.0L
For those wondering just how much electric they use,
I hooked up an analog amp gauge with shunt. Easily to read to about .5 accuracy, good enough for this...
I hooked the gauge on the alternator feed wire going to the main fuse box where the 70 amp main fuse is.
With a fully charged battery, increasing rpm with load to ensure that alternator was able to put out what was being used:
DRL Disabled
Engine running, no lights or accessories on: 14.5 amps
Parking Lights: +4.5amps
Full Lights + 13amps (high beam no real difference)
Fan 1 +5.5
Fan 2 +7.5
Fan 3 +13.5
AC enable +5 for Condenser Fan
Turning on EVERYTHING I could, including rear defroster & Wipers, consumption was 64 amps. Not bad for a 55amp rated alternator. Battery connects on the fused side.
