I did the
I did the fwd test with ignition on but the engine was off (got 9.5 volts). Then I took the Fwd fuse out and ran full throttle in 1st gear (got 6.5 volts). And yes, all 4 wheels were off the ground. Was that a mistake? Should I do the 1st gear test on the street? ThanksDid you do these tests with the ignition on but the engine off? It sounds to me like you were running the vehicle on the jack stands, which would likely account for your variances.
