THE PHOENIX and strange happenings

04-19-2010, 07:21 PM
I filled my gas tank today and on the way home the Gas Guage reads 1/2
and the Temp Guage reads just off of cold (1/4 the way up)...!

Car runs fine, but now both guages run low. Radiator is full.

My guess is the Alternator isn't charging - low voltage.

Are those Guages voltage sensitive ?

Am I correct ?

Will look at voltage (old battery and cables) to check it when I have time.
Teaching duties have me grading papers like mad - I'm behind....

Alternator has a warning light of it's own that should be lit up if it has failed. I suspect a bad ground.

I put a Voltmeter on the battery and started the Phoenix.

15 volts.

Both Gauges are back to working normally.

Thus - I suspect my Ignition Switch is starting to go T.U.

Or maybe some relay somewhere.

Drove 35 miles to work - all is working nominally.

If I remove the Temperature Gauge Sensor wire near the Thermostat and
ground it - does the Gauge go to the top or the bottom ?

Doesn't hurt anything to do that - right ?

Either my Temp Gauge Dial or my Temp Sender Unit is variable (squirrely).

I want to finger out which is going bad.

Otherwise all seems well and I'm back to getting around 46 mpg until the weather
warms up - then 50 mpg.

if you ground it the gauge should go to full hot, just don't ground it to long, you can burn the guage out

Every day now, the Temp Gauge goes to a different spot, stays there like a
rock...but different every day. No big deal - just annoying.

Used to always go to the same place.

I think I have another sending unit from the Pull-n-Save - have to find it and
see if it works better.

Actually I have no idea what is going on.....

You have a bad ground or 12 volt supply to the cluster. No point in starting to troubleshoot the temp gauge when the gas gauge is malfunctioning too. Has to be something that is shared between the two gauges.

I think it is my Karma to have automobiles with intermittent connection

It eventually comes around to this crap where it DOESN'T ALWAYS happen.

My Jeep and Suburban and WV Bus (years ago!) did stuff like this and I spent
Butt Loads of money trying to fix them.

Especially electrical problems !

When I went to a mechanic, the bugger worked fine.
A mile down the road, came back to haunt me.
