Hello,

I'm having some difficulties with the glow plug relay. I replaced it about 6 months ago, and now every so often, the relay does not come on and neither does the glow plug relay light in the dash.

The only way to fix this problem, seems to be do disconnect both electrical connectors from the timer and replace them back in 10 seconds

Now, the light will come on and everything is ok.

This only seems to happen intermittently?

Anyone seen anything like this before?
