In getting it ready to use I think all I'll need to do is clean the windows, put on a new mirror, and install a working pressure gauge. My question involves the clip on the side of the body. I assume the original power cord had no ground wire and the clip was for attaching one.
The modern power cord has a ground wire that's hanging loose. I assume I can attach it at the nut where the bolt holding the clip also holds the transformer base. Being electrically challenged, I thought I'd better ask and be sure I have it right.
Any place on the outside of the box, or connects to it, would be a good place for a safety ground. Basically you are providing a "shock path" for any stray current that might energize the outside of the tester (sheet metal box). Just give it a place to go with that ground in the cord.
make sure you have a functioning, testable pressure valve and install a shield on the window!
Ive never seen one of those. Could someone explain how it operates
It allows you to see how a plug performs under pressure - simulating compression in a cylinder.
Just attach that green wire to the metal case. Then make sure you use a grounded outlet.
I really miss that Champion that got lost in time.
Real nice unit also it sand blasted plugs. It had many adaptors for any thread size. I remember most plugs took a dump around a hundred pounds looking in the mirrors. My guess it was around 1935 when my father built the new shop still in business today...
Could perhaps the fact that the spark plugs are using the same metal as the now attached electrical house plug wire cause a problem? Guess you'll find out. Just saying that it may have been left off/disconnected for a reason.
You may have to replace the glass seals.
Hi Steve, I restored one a number of years ago and its in regular use in our workshop. Do not recall that clip on mine but I did replace the transformer and earth the chassis, more details via my blog https://1925modeltford.wordpress.com/2015/12/08/champion-spark-plug-tester/
