engine hour meters

What would cause both Hobbs hour meters to stop working? I check the power and all seams to be OK. They have not worked in about 1 year. The gauges are Stewart Warner, analog display only 1020 hours displayed.

Welcome to the forums!

Usually it's corrosion at the wiring connections. If they're connected with blue clamp-on connectors, cut them off and connect them with the proper spade terminals. If they already have spade or screw terminals, clean the connections with fine-grit sandpaper.

First, turn off the battery or pull off the positive battery cable.

Ricks advice for getting your hour meter working is on the money.
Sometimes wires corrode inside the insulation also. You may need to check to make sure current is flowing to the hour meter after you clean the connection.

Hobbs Hour Meter

I read your post of Jan 09 regarding the Hobbs hour meters.
I have exactly the same problem, except mine are dead at about 1400 hours.
I have verified power, correctly polarized, to the meter and verified a good connection at the meter.
The likelihood of both going out at the same time seems so strange on such a normally bullet-proof item.
Did you ever come up with a solution other than replacing them?
