Hi all.
I noticed a month ago when first starting the engine on the hard that the temperature gauge was not working. I wasn't particularly worried about it at the time because everything else was working fine and plenty of water was exiting the exhaust with the by-pass both open and closed. When we went down the Danvers River, the first time the engine was under load, the gauge didn't budge. Now we're done with all the other chores and it's time to get the gauges working reliably. I don't like the idea of not having a reliably working temperature gauge.
Tonight I ran a jumper from the sending unit to the gauge sending input terminal to see if it were a wiring problem. No change. I ran another jumper from the ground terminal to the engine. No change. I'm sure there is power because the other gauges are working, although I'm not sure how to use the multimeter to check that without blowing its fuse.
My deduction is the sending unit is bad. Am I missing anything? How best do I determine whether the gauge is getting power?
Thanks in advance.
