12v Super Glow experts

[wesintl]

Well, I finally got some time to replace my relay rod and troubleshoot the glow system this weekend.

with new glow plugs I get roughly 7-7.5v at the plugs at super glow then it drops to 4ish. I'll have to actually time it but then it drops off to 0. This is what I would expect.

Not sure if it why it burned out my reserve plugs but now it seems to be operating as it should.

this super glow thing got me drove crazy also . I have a 24v system and am getting 20V on the bus for 5 seconds then a click and my light goes out then down to 11 volts for 5 seconds and then a click and 0 volts . The truck starts rough like shake apart rough. My plugs must be burnt out or something I will have to pull them and check, never done this before it should be intresting .

That's pretty much how it's supposed to work.. I can't remeber if it should be higher voltages (24ish/12ish). What volt plugs do you have? they should be ~14v

To find more than 12V at the busbar you must be making your measurements with the engine running. Is that what you're doing?

(I'm confused as to why your engine would be running! Sure .... I admit that a fully charged battery may have higher voltage than 12V but it's not normal to be able to measure more than 12V at the busbar when you are drawing a lot of current off your battery with your glow system prior to cranking your engine ......... even if the battery is fully-charged and in top condition.)



Does this represent your wiring?:

If so, you shouldn't be able to get battery voltage at your busbar with No. 1 relay disconnected!

And AFAIK number 9 terminal simply tells your "timer" when your engine's running by sensing the alternator output.

Hi! I have problem with Glow plug timer connection. I am doing a new connection 9 pin timer 078451-0152 to toyota Hilux 1987 2,2 Diesel engine.
Do you have wiring diagram for 9 pin card ? I am not sure are they same with 10 pin one.
