So i stuck a new autoguage water temp guage on my car in the weekend, put a sender in etc. etc... wired the thing up..

Fire the car up, the guage lights up, but instantly reads 50-51 degrees, and doesnt shift...

so im guessing ive got a short somewhere, for it to give that reading. is there anything obvious in the car that would give that reading? or shall i just pull it apart and wire it again?

providing you used the sender that came with the guage and wired it CORRECTLY

it should work fine, just double check your wiring

yeah i used the supplied sender, and i am an electrician.. although not an auto electrician, lol.. so i hope my wiring is correct.. will take it out one night this week and re-check..

i just though that since it reads 50 degrees, as soon as power is turned on, someone might know what ive got it earthed out on.

post a pic of how and where you mounted the sender.

its just in one of those el cheapo radiator hose adapter thingy's. ( cut the hose, put the adapter in, screw in the sender )

yea those senders have 2 wires, i just ran both back to the guage when i did it and powered it off the ign under the dash, cant go wrong really that way

Faulty sender could be the problem.

Autogauge havnt had the best quality control.

im guessing its an electric sender??

If so the sender it self needs to eb grounded.

Two wires on the sender,

one should be wired to the sender terminal on the gauge,
and the other to earth not power.

you need to run one wire to the gauge and one is a ground thats why your reading wrong

by **Jonno2002** » Thu Oct 02, 2008 10:35 am

looks like i have to explain myself in full yet again, i ran the wires back to the guage, 1 to signal and 1 to the ground term on the guage then grounded the guage under the dash....

by **o0hoe rolla0o** » Thu Oct 02, 2008 10:44 am

i would grond the sender wire as close to the sender as i could. the senders work on resistance through the ground. the longer the wire the more resistance your getting your not working with 240v here the smalest amount of resistance can screw it up.

So i took it out in the weekend and double checked everything...

Its working fine now, or seems to be..

Just curious as to what the average temperature on a Blacktop 20v would normally be?

my silvertop used to sit on around 70-80

by **Bradles** » Mon Oct 06, 2008 10:29 am

coolio.. the highest mine reached was about 85 degrees, but that was when hitting 7-8k in each gear etc, so must be reading reasonably accurate.

by **o0hoe rolla0o** » Mon Oct 06, 2008 10:34 am

yea i got mine up to around 100 a few time's i never hooked up the radiator fan and was sitting in McD's drive through :oops:

85 is fine
