Thanks for the info Ross, just don’t want to start pulling on things that I’m not 100% sure how they come apart, 👍Have had it off but not for a while, from memory you need to depress a tab to release it, but it still doesn't just pop out, especially if it uas been in for years.
No power at buzzbar, removed glow plugs (new)to rule them out, checked with multi meter also all good there, just no power at buzzbar. Led still doesn’t come on , checked wiring for led, earths , glow lamp dash light comes on, just got me stumped, doing everything I can as I don’t want to take it to an auto elec unless it’s a last resort! Glow plug timer works as normal, car starts easy, no smoke at all considering mafs voltage are high as I haven’t put jaycar modifier back in.Why do you wish to open it? It is just a connection point, nothing in there bar wires and pins.
