Engine alarm light on

[Gary Miller]

Steve,

Hang in there, we'll get you all straightened out before your first
rally.

The buzzers can be confusing since they're all the same type and
located in the same area. Fortunately, there are lights associated
with some of them, and things to check on with others to determine
what buzzer it might be.

The engine alarm light (and buzzer) will illuminate for an overtemp
of 210 degrees, oil pressure below 6psi, or low coolant, assuming all
senders are working. Each one is a different sender than the gauge
associated with it, so if your gauges are happy your engine is likely
happy. You now have one of two problems. Low coolant, or a bad wire
to a sending unit. The most common cause is the low coolant sender
wire, which is located on the top curbside of the radiator. Check it
for shorts and etc... The other senders are a bit more difficult to
access but the wires are much better protected. More on them if you
need it.

It's curious that you don't report the engine alarm buzzer being on
with the light. Perhaps this is your intermittent buzzer and the
light was unnoticed before?

If this all gets to be too much, swing open the headlight door on the
roadside and have a look at the wiring for anything obvious. If you
locate the offending buzzer, note the wire color and get back to us
with a post. Be careful with the bolts on the access panels as they
are sometimes seized and will possibly break off the nuts holding
them in place. Then they just spin freely and you'll have to cut
them off without hurting your paint. Penetrating oil to help remove,
and anti-seize for installation.

Best of luck,
