Another Issue - Roger McEwan Temp Gauge
All, ordered a Roger McEwan oil temp gauge from Direct Harley Parts earlier this week to replace the useless ambient temp gauge. This amongst other things was to be my Saturday project in preparation for a long weekend trip next weekend.
I noticed when first unboxing the gauge is was setting on about 220. Interesting, but I have seen electronic gauges behave this way before. I install the sending unit (no sealant). Route wiring in wireway under gas tank and connect everything to gauge as per instructions.
Double checked everything and mounted gauge to inner fairing. Plugged in the main fuse and switched her on. Nothing. Gauge remains on about 220. Check everything again. Light come on in gauge so I know it has power and a good ground.
I think I have a bad one out of the box. Any other suggestions before I have to wait until Monday to call someone?
Thanks in advance,
Lilman

Will do, about to put the tank back on. Trying to avoid putting the outer fairing back on and having to take everything back apart to replace this thing. It is a pain to get to.

Not being a smart ***, but it sounds like you answered your own question, and it sounds like you should went w/your gut instinct from the beginng when you saw it was set 220.
That gauge is not easy to get in either is it?
Too bad you have to do it again....Maybe you can get lucky and get it to re-set?

No dice.....got everything except the outer fairing back together and fired her up on the stand. Over about 10 minutes of constant running and about 3 start - stops, no change whatsoever. Guess I'll be calling Direct Harley Parts Monday morning.
Lionsm....you are correct, this thing is a pain to get at!
Time for lunch and a cool off. Already almost 100 in SE Georgia.

Try this; Take a strong magnet to it and see if you can alter it. I did, as I when I decided to go for a ride today and saw that my temp gauge registered 200, before even getting on the bike, and I said WTF?
I then took a magnet to it and then got it to go back a little bit. So now I am beginning to wonder whether or not I was runnin' about 30 degrees hotter than I thought I actually was..
Seemed to level out after I got going though, but still seemed high;
starting to wonder if it's all that accurate?
Going to get another type of one of those laser gauges and double check it.
Anyone know what they call those types of gauges?

A laser temp instrument would give you head temp or cylinder temp depending on where you aimed it but not oil temp. I think head temp is roughly 30 degrees higher than oil temp. A meat thermometer in the dipstick hole would work but care should be taken that it does not break or get dropped in. Best if you had a friend that would loan you a HD dipstick temp gauge.
