I know this has been done to death before, but I have a problem that I don't think has been covered yet!
I have a 1993 on 2.8td engine in a 1971 Land Rover, and have been slightly confused by the previous owner's interpretation of good wiring on many counts!
My glow plugs are connected to the relay in a way I can't fathom. I have a battery connection going to a momentary switch in the cab. This goes to the big blue relay on my baulkhead. One other connection is switched, and the other two in the 'standard' relay part aren't connected at all. Then I have another connection from the battery that goes to the big bolt on the relay. The smaller bolt is connected to the busbar at plug number 4. There is also another connection on this that goes to a second relay.
This second relay appears to be connected only to the warning light on the dashboard. This all seems a bit wrong!
There are no other connections to the busbar, and I'm guessing there should be another connection from somewhere to the plug no 3 positon.
The current configuration works, so long as I keep my finger on the momentary switch until one of the relays clicks off, but I'd like a more 'normal' system!
Could someone please tell me how it should be wired up, on a terminal by terminal basis (a picture or wiring diagram would be brilliant).
Secondly, there is an electrical connection in the gubbins that is the turbo. I've connected 12v to it and it clicks, so I'm guessing its a solenoid. Previous Owner didn't see the need to connect it up. What does it do, how should I connect it, and does it make much difference to the performance if it is connected?
Thanks in anticipation of some helpful answers!!!
