Oh boy! Marlin P Jones is still out there kicking! Almost 30 years ago their operation was once located right next door to a warehouse condo I owned in Riviera Beach. Great people and a great operation, they always had some of the coolest stuff if someone is a tinkerer or an inventor type. I'm still using a tube of Tef-Gel I bought to use on aluminum boat stuff all those years ago. Small world.

If you got another shunt and a selector switch, you could monitor glow plug current and get an instant indication that one is burned out. ( If the GP are in parallel )
$ 18.00 now, on sale for an unknown period of time $ 13 . They have lots of other meters and much more in the way of electronic goodies.
