More installing new guage

[amweath]

As I was driving my coach home I noticed the tach moving all over
the scale. I'm going to be installing the new oil temp guage. I will
also
take a look at the tach. However, I don't really know exactly what
to look for. I assume it's electric. What drives it from the engine?
I have a Jaguar E-Type and it uses a small AC generator to drive its
tach. Does a 6V92 have something similiar - something I could measure
the voltage out of and determine at which end the trouble is? Where
would this sender be located.

I know it sounds like, from the amount of my posts, I'm having a lot
of problems. I'm really very satisfied.

1 The dash air works and converted to R 134
2 The leveling system works
3 The overhead air and heat works
4 The LP and electric furnaces work.
5 All the water systems work ( hot, instant hot, etc.).
6 The generator works
7 The microwave works

The only thing I really havn't tested is the frig. Its new so i'm
not really worried.


Thanks in advance
