Re: KP/CM2...VDO gauge questions

[Night Shadow <soltwede@privateI.com>]

I have one of those guages too, and no, the sender works totally opposite
of the normal VDO.  It varies - to the guage but the opposite of what
other senders do.  A normal VDO sender gives the guage less resistance to
ground ( - ) as the oil pressure rises.  While these wierd KP/CM2 ones
give MORE resistance to ground as the pressure increases...

So you see, with no guage lead hooked up you have infinate resistance to
ground, therefore a pegged guage.  PLEASE let me know if you find a source
for the correct sender.  Mine is shot.
