Glow plug timer relay

Feb 14, 2020 4 Replies

This seems to be misbehaving on my ATV (this has a 3 cylinder diesel, badged Caterpillar but presumably Japanese, and has a "glow plug on" light). From a quick eBay, I can get one for a Freelander for £15. There's a separate relay on the engine to switch the glowplug current, I can't see any obvious reason why a Freelander timer should not work. (Obviously, I may have to fiddle with the terminals but I have a workshop manual for the ATV so it's easy to work out the connections)-.



I did just wonder whether to fit a manual switch, perhaps a "spring off" one


once it runs you shouldn't need them on anymore, so a simple switch or push button would be ideal for anyone with a little knowledge, the timer is for the less mechanically minded plug and play generation.

Not just that I think. Many diesels keep the plugs running for longer than the panel warning light would have you believe for emission control. For an ATV I?d just have a simple sprung ?push to make contact? button switch though.

certainly, but this is not a california car, even if you were to remove the glow plugs entirely and start them on easy start a modern diesel would still make the emission standards needed for the mot.

The OP states that it is an ATV, so it really doesn't matter.

Thanks. I'll have a poke around. My mechanic friend also suggested it might be worth checking that all three glow plugs still work, which means whipping off the "bus-bar" that daisy-chains the power from the first to the rest.

The disadvantage with a simple switch is that access to the back of the dash is a bit fiddly, whereas even if the landy one has different sized terminals these are fairly accessible.
