Back up lights on in drive.

[Zeroman]

I attended a car show & cruise this past weekend. Throughout the day I must have had 20 people inform me that while in drive by backup lights were on.  Other than replacing the neutral safety switch I really can't think of anything else that could be causing this problem? How do I bench test or troubleshoot the NSS?

ck for continuity across the 2 outer terminals . It should only have continuity when in reverse position.

if thats ok, ck for a shorted wire in the circuit
