Ford/NH CM222 - No Fuel or Temp Gauge

[G_ynot]

Both fuel and temperature gauges had been working fine. Parked the machine and at the next use neither gauge is working. Tachometer works, as does the head light and glow plug indicator.

I've ordered a manual off of ebay, but I don't even find any fuses on this unit. Nothing in the engine compartment so I opened up the steering column and nothing in there either. Being it is of old age, I thought maybe a fuse had failed being both gauges quit at the same time.

Welcome to TBN!

If I remember, I believe the fuses are on the RH engine compartment, but I would have to look in the book tomorrow

A lot of the old Fords used a voltage reducer on the gauges. A small metal rectangular unit that plugged on the back of the gauge cluster. My guess, I would say that is the problem.

Do they use a common ground?

CMs were Shibaura built, different system.
