Subject:VDO Guages not working
From:Jonathan Poole
Date:Mon, 1 Oct 2007 11:36:19 -0400

So after another full weekend of working on my new van I finally started the
engine up.  Boston Bob did it right as it started and ran perfectly through
the first 30 minutes and two oil changes.

A big part of the work this weekend was the wiring and installation of my 3
vdo guages cht, oil temp and oil pressure.  The oil temp is working fine but
I have questions about the other two.

First according to my infrared therm. the heads near the intake never went
above about 200 so was that hot enough for the cht to register?  The needle
on the cht guage didn't move ever.  I hope to drive the van soon, at what
temp should the guage register?  Are there ways to test the guage/sender.
The sender is mounted under the #3 plug.

Second, the oil pressure guage goes to max as soon as the key is turned on,
(12v goes to the + lead terminal)  Even if the sender wire is disconnected
it stays pegged.  I have tested the sender wire and it is connected.  It is
from the Bus Depot wiring kit and is one unbroken wire from the sender to
the guage.  The sender is the dual output type with two poles one labelled
"g" the other "wk".  The stock oil light goes out as the van is started and
appears to be functioning normally.  I have the guage on "G" and the idiot
light on "WK".

Any help/suggestions with these problems would be greatly appreciated.

Thanks,

Jonathan Poole
