manual glow plugs

[gatorman21218]

so here's a thought...

Manual glow plugs are an on/off kind of system. You control how long they glow. Automatic plugs burn every time, no matter how hot the engine is.

So can I get the best of both worlds? A manual system but it turns off when it reaches temperature? I do mine for no longer than 10 seconds. but in the morning I think its not enough, yet I'm scared to go any longer and burn them out.

So what i'm looking for is a system that is controlled by a toggle switch, yet acts like the factory relay when activated.

how well does the engine start on those mornings?

I mean it starts, but lots of missing and and moaning and smoking. would i be safe to bump it up to say 12 seconds?

mine stays on for all of 12 sec in <40*F temps. sometimes it stays on for 15 sec.

tie the ignition power for the glow plug relay into the cold start circuit. The GP will only function on auto when the block is below whatever temp kicks off high idle.
