[TR] TR6 OD dash Indicator light idea

[Tony Drews]

In my race car, I had one of the indicator lights on the dash be 
parallel to the side of the relay that powered the solenoid (most relays 
had two outputs so it was easy to wire).  But it was not to let me know 
when it stuck on - it was more a quick troubleshooting deal for when it 
did NOT engage.  If the light came on but OD didn't engage it was the 
solenoid or OD - otherwise it was an electrical problem.  Turned out 
that when the OD didn't work it was ALWAYS an electrical problem.  :)
