We have a winner!!!
Went out and turned on the 12 dome lights and adjusted the brightness!
Yeah, 12 dome lights and 6 of those overhead lights you see in front seat of police cars (for those that have had the luxury of riding uncuffed in the front seat)
It was an ambulance and the more light, the better... I'd think
The other night I had been dinking with it, and saw it did nothing so I left it alone... The next night I used the dome lights and saw they were dim....
Dismissed it as "more crap to work on, check for bad ground)
Btw, I did Google search different combinations of OHMITE before I decided to give up my coupon
And saw some rheostat related stuff, but dismissed it, thinking I was opening a valve for air or hydraulic
