I got a new ignition switch last week for my '96 Defender 300tdi.
It said it was OK for that year but it the old one only has 4 connections as opposed to 5 on the new one.
In addition, the old one is all 6.25mm spade terminals whereas 2 of the terminals on the new one are the wider 9.3mm.
I'd be happy to adapt & put new connectors on, but I can't make any sense of the switching on the new one.
The old one has a supply on pin 2 which connects to pin 5 on 'Aux', pin 3 on 'On' and pin 1 for 'start'. Nice and logical!!
The new switch has ...
- pins 2 & 4 connected when off
- pins 1, 2 & 3 connected when 'on'
- pins 2, 3 & 5 connected for 'Start'
and nothing at all connected in the 'Aux' position
This last is the problem, the rest I could work around!
I could take 2 or 3 as the input; 1 as the 'on' feed and 5 as the 'start' but I have no power in 'Aux' which feeds things like radio, heater, etc.
(... and why have 2 & 4 connected when its off???)
I'd be very grateful for any thoughts and advice. I know I can go back to the (eBay) supplier but I've taken the old switch out and thus I'm off the road till I sort his out!
Thanks
Steve
