On my 2002 60hp merc outboard, the temp guage doesn't work.
Per a previous thread, I applied 12v to gauge and it pegged all the way to the right as it should.
Reconnected the sender wire and turned on the ignition. Checked voltage at the sender terminal on the gauge and had 9.5v, engine cold. When engine warmed up voltage at gauge sender was 11.5. Needle had not moved at all.
Bad gauge?
Does the gauge sender run on voltage or should I be measuring impedence (ohms)???
Thanks in advance for any help.
