Well the truck passed it's vehicle inspection and is now registered in the UK A few advisory notes from the mechanic suggesting new upper and lower ball joints plus the drive shaft centre bearing was worn. So parts being ordered from CP. The truck ran out of fuel during it's inspection, however it was showing just over half a tank . The seller told me he had replaced the sender unit but was showing 1/4 when empty after he had done this!! Looks like it hasn't improved at all. So do i need to a new fuel gauge (available thru CP) and is it a straightforward job to replace in the dash instrument panel? Also another puzzelling point is the main fuse (35A) from the battery to the truck's electrics keeps blowing when the truck is running. It is intermittent. Do i have a short somewhere? Thanks for your help guys. Merry Christmas and a Happy New Year to you all
Congrat's on the inspection! I would suggest pulling the fuel level sending unit and manually activating the float to see if the guage corresponds accordingly. You can then check the ohm's on the sending unit to see if it is within the correct range of 0 to 30 ohms. As for the fuse blowing I would trace the wires starting at the battery to see if there are loose connections. Especially down near the starter and around the alternator.
David the `65 model used a 30 ohm gauge and sender, to test the gauge you`ll need a small cheap volt ohm testor, with no more that 1.5 volts to test the gauge ohmns or you`ll burn out the gauge, then teat the sender. The `66 models went to a 90 ohmn set up so you might have a 90 ohmn sender in the truck and need a 30 ohmn, and as John said start checking for loose or broken wires under the hood.
