[C38] Overheat False Alarm

[Max Soto]

David,
What do you mean by "again"?? What happened the first time and how did you
solved it?
If the temp gauge rises all the way up, check that the wire coming out of
the sender is not touching anything else on it's way to the gauge it maight
be  making ground somewhere along its way, if not, check your sender and the
gauge)....

Regards,

Max
