The 76 is the update to the 75, with improved circuitry so that it can be used on 24v systems as well. With user feedback, we beefed up the circuitry and changed the switches from momentary to toggle. The tool is used to test the complete circuit. Shows power or ground from battery to relay...
Yes, it works that way sometimes. We also develop in house or another company may come to us and ask us to develop something outside their wheelhouse. The "relay circuit pro" you mentioned was in fact an idea of a school teacher in Iowa. If you ever have any questions or comments (good or bad)...
I would advise against the other unit, as you heard hollow rock say above, there are good companies and bad companies. The least they could have done was get his program right if they were going to take it.
We usually give the mobiles a year or so exclusive, I would expect it to be available in the Fall. Hard to say what cost will be as there are so many resellers. Since it is not a Snap On proper item the price will go down, but not as much as you might hope.
Hello All - Wanted to step in and answer the question of the OEM. That would be us at Cal-Van, we are a specialty tool company based in Greensboro, NC. Let me know if I can be of any assistance.
