Multi meter set to continuity. One contact on the earth pin of the games plug, one on exterior metal parts. I get continuity on the external metal of all my games except, when I test the shooter rod housing on one machine. Does this matter? Does the shooter rod housing need to be earthed? If it should, and this is a problem, what do I need to check and fix to solve it? Thanks. John

Am I well grounded?

What game is it John? On old games with metal housings it's generally earthed via the lockdown bar receiver through contact between the two inside the cab. If your lockdown bar is earthed then should be easy to sort 
Thanks Chris, @ronsplooter . It’s my recently arrived Earthshaker, which I’m not playing yet as I need to check fuses, re rubber and clean it up.What game is it John?

think of all the unearthed EMs. no problem 
It should be , and shouldn’t be hard to fix.
Tbh it’s belt and braces …in the tiny chance that somehow the shooter rod housing becomes live.
Unless you're thinking of taking it to a show or siting it then you should be fine as Alan and Ive have said but if you want to sort it then run a short length of wire from one of the screws that hold the shooter housing in place to something else that's earthed, lock bar receiver or front right leg plate are your best bets
Thanks for all the sound advice. I’ll see if I can ground it and not lose any sleep over it. I had some small children playing on the machines the other day and it just struck me that their parents would probably be miffed if I electrocuted them.
In fact the only coin-op injury I’ve ever been responsible for was with an Allwin spinner. It was screwed to the wall of the basement stairs. A small visiting child cranked it so hard he pulled it off the wall, taking him and the machine down half a flight of concrete stairs. The machine was undamaged. The boy less so.

I´ve disassembled the shooter rod some days before to apply a new, chromeplated spring. I have noticed a nylon tube (similar to that kind which is used in the flipper coils). The rod is guided by that nylon tube - it´s hardly surprising that there is high ohms.
