[DeTomaso] Electrical questions--HELP!

[Christopher Kimball]

I would think that may be my problem, too, except the fans weren't running 
when the motor first started and yet the ammeter was almost all the way over 
to the right straight from the start.  Once the fans kicked in the meter 
really pegged.

Good luck with your fans, let me know what happens!

Sincerely,

Chris
