Hi Scott
I'm sorry if i mislead you... I'm used to the LUCAS senders , you can remove the lid on them and get to the innards
OK the GM delco remy ? units . Yes you can test it without pulling it apart.
Put one lead on the HOT 6V connection and the other lead anywhere on the sender body , make sure the connections are clean . Thats it ..simple.
Sometimes the wire resistor and the wiper inside becomes oxidised and intermittent ..you may have to drill rivets to pull it to bits and clean it if it needs it.
One important thing to remember is: the sender and gauge rely on the truck body for a earth return ..It's far better to provide a seperate earth return wire for the sender to gauge unit in the dash ... just use one of the sender mount screws and run the earth wire alongside the HOT wire to the gauge where it is screwed onto the gauge earth mount
