[s-cars] battery problem - alarm?

[Bob Frizzell]

Teddy,
I would bet you have the relay problem as described.  When I first got my
car I had the car in for an out-of -province inspection and the battery went
dead.  The mechanic there and I hooked up an ammeter to the battery, pulled
every relay and fuse, including the radio, to no avail.  I only fixed the
problem when I got on this list and did as described (clipping the T16/8
yellow wire).  I suggest you hook up an ammeter and start pulling relays
but, as stated, would bet on the relay problem. Losing the closing feature
is not a big deal. I'm not sure about the alarm.
Bob
