Wile7 Posted June 22, 2014 Share Posted June 22, 2014 Hi chaps, Purchased these shift lights a few years ago (new) and finally got round to installing them this morning . My problem is that when I connect to the coil using the spare spade connectors the car does not start.... Disconnect the coil and things are fine. I've used a scotch block to connect into an earth - could that be an issue? Any advice welcome please Dave Link to comment Share on other sites More sharing options...
Member Jonathan Kay Posted June 22, 2014 Member Share Posted June 22, 2014 How many new connections are there altogether? Jonathan Link to comment Share on other sites More sharing options...
Wile7 Posted June 22, 2014 Author Share Posted June 22, 2014 Hi Jonathan, Aside from the actual 'shift light' LED module there are three wires; one for positive and one for negative on the coil and one for the earth (according to the instructions)....

Member Jonathan Kay Posted June 22, 2014 Member Share Posted June 22, 2014 My first guess is that it's taking the voltage at the coil terminal to earth. But that can't be a fault in the earth from the module. It could be anywhere else, including inside the module. 1 Check connections are as intended. (Again!) 2 Can you check the positive from the coil outside and inside the module and see if it's shorting to earth? Are the instructions available?

Wile7 Posted June 22, 2014 Author Share Posted June 22, 2014 Will do....yes, wired in as per the instructions. That's what is frustrating 😬 Link to comment Share on other sites More sharing options...

But that can't be a fault in the earth from the module.This might not be true, by analogy with that strange fault with brake lights where a bad earth causes an unusual earth route to occur. I'd put that Scotchlok back on the list of possible problems. Jonathan Link to comment Share on other sites More sharing options...
