Internal wiring of BJ40/BJ42/HJ47 glow relay (Manual glow)
Hey. Let's have a "free-for-all" on the subject of the glow/start wiring that was fitted to diesel cruisers produced from around 1977 to 1983 that are "manual glow" (as opposed to "superglow") and are "with EDIC". The most common models affected here are the BJ40, BJ41, BJ42, and the HJ47. (Perhaps the HJ45 too - but I never hear much about those cruisers on the 2 forums I frequent.)
By "free-for- all", I mean a "no-holds-barred" discussion where anyone can say how they think the glow/start system on these cruisers was REALLY wired by the factory and no-one will get offended. - In other words - I'm after what you think the "as-built" wiring really was.
I'm starting this separate thread because I note the discussion occuring in GregFrench's current thread. But I'm reluctant to enter that one because I don't want to divert its course. And the last time Greg sort help, we ended up discussing too many sidetrack issues (totally my fault - I know) that were unrelated to his vehicle or to his particular problem. And my "staying out" allows a fresh approach to be taken there which may well be successful. (I'm thinking of the previous thread's failure to solve Greg's "glow system issues".)
But at the same time, I see "the as-built status of our glow/start wiring" (including the internal wiring of the glow relay) as an important issue to thrash out (and if possible to gain consensus on).
Anyway here is my glow plug relay (lefthand one):
And here is the latest diagram (based on a 12V 4-cylinder diesel) that I've modified to what I believe best represents the "as built status" of our glow/start systems. As you can see, it includes the internal wiring of components so you can actually "read" what happens:
I can easily "read" how my glow/start system works from this diagram and there are no contradictions (that I'm aware of) between what I read here and how my truck behaves in reality! Now this is something I've found I can't say for any FSM diagram that I've yet come across. (But I won't take offence at anyone's efforts to support an alternative wiring diagram, to suggest changes to mine, or even to trash mine completely.)
