[DeTomaso] Electrical Issues AGAIN

[cengles at cox.net]

Dear Richard,



               I am no electrical expert, but I have an opinion! 
"Everything" goes through the hazard blinker and I have had it go wonky 
on both of my Panteras.   I don't recall them having the same symptoms 
as you describe, but there is some similarity.   The gauges should not 
be part of a hazard blinker malfunction, AFAIK.

              Is it correct that after you properly connected the 
battery that all the electricals were back to their pre-paint shop 
normal function?  If yes, then I think that the hazard switch is 
suspicious.  The other more elusive possibility is the common grounding 
problem that can manifest itself in numerous ways, I am told.

              I hope SOBill has the answer.



                               Warmest regards,  Chuck Engles
