The following site has instructions:

I forgot to mention the sender a a Dipstick unit with the blue top and two spade terminals..Thank you Wolfgang for the replay ..went to that site but no mention of instructions for a Dipstick sender
I don't have one, so this is a guess, but any sensor that works on resistance needs a ground. A normal sender (sensor) gets it's ground through the threads and the case. I would assume a dip-stick sender would need a ground wire to operate- hence the second terminal...
Nope........the sender usually gets ground through the case, but what I bet he may have there is a sending unit with a second terminal for an idiot light. Some of the senders support BOTH a needle-type gauge AND an idiot light to get your attention when the temp is too high. It looks like one of the oil pressure senders that support both a needle-gauge and a light (for low pressure).
Of course, since it is a dip-stick style sender, it may just have one terminal for the gauge and another for ground (to make sure it gets a constantly good ground). In that case, EITHER terminal can potentially be grounded. If that is the case and you attach an ohm meter to the terminals, they should show several hundred ohms between them and it should change if you heat (or cool) it.
BTW: Berg sells a dip-stick sender that makes your oil pressure light come on steady at 230 degrees (F) or something like that to let you know you're too hot - maybe you have one of those?
Bill: are there any markings stamped onto the sender at all?

The only marking is that it is a VDO and 150C one spade is brass and the other is copper..I assume that one gor=es to the guage and the other to ground and at the guage one of the spades goes to a fuse ( Besides The ones for the lamp) I just not sure whiuch 9is which and don't want to burn it out.As My winning bid was $51.00. I sent the seller an E-Mail for an answer to my questions .But no answer as of yet.Hes got his money I got the part and say-la-vie..Mayby next month at the club meeting someone has had one of these or is using one ..Thanks guys anyway...Bill
