Al and I are trying to modify the Digi-panel to also measure the fuel line
pressure to the injectors on our Howell TBI. This looks like it will work
and we will report in the future. Doing this project we learned some
things about the oil pressure senders and I am posting it here and on my
web page. Most of the senders in the GMC parts interchange book are not
correct. Most of them are switches for dash lights not gauges. The
following text gives a source for the correct sender.
DIGI-PANEL MODEL J
PLEASE REQUEST MODEL J FOR GMC MOTORHOMES -they are made specifically for
GMC's -
plus the NEW install instructions will be included --EACH one of you will
need to make your own
arrangements for payments -- Art takes Credit Cards or you can mail the
check to him Pete
The Model J has been modified to use the same Oil Pressure sender that the
dash Gauge is using. This
makes it easy to connect the DigiPanel. The Dash gauge supplies the
voltage to the sender so that the DigiPanel can
read the oil pressure. The dash gauge must be connected for the DigiPanel
to read the oil pressure.
The original DigiPanel supplied a constant current source for the oil
pressure sender and uses a
separate sender. The sender to use is :
NAPA OP6636.
These are also available from General Automotive and DigiPanel. This is
the sender to use for the Dash
gauge in the GMC. gene
