Diy Immobiliser

[Guest Battery Bill]

As I mentioned in another thread most of my engine messing knowledge is from the marine side - its now standard practise to use crimp connectors as soldered or screw ones fail more often. To be fair there is more damp around in boats and we also use fully tinned wire.

And these are not the cheap and nasty ones you get in Halfords in a pack with the pressed steel clamp, they're proper ones that need putting on with the right tool that you ratchet shut and have sealant in the back of the connector.

A proper crimp connector doesnt fall if if its the right size for the cable and put on with a ratchet crimp tool, not pliers or the 4 quid specials.

 

Funny I spent most of this afternoon messing around with failed Crimps on a double glazing rig (The good quality type, not the £4 specials) I agree with BJ twisted wire then soldered is the best method by far

Cheers Mat,

 

Well that diagram makes me feel a bit out of my league. Im not 100% sure that I've got the right DPDT relay! Has anyone else made this immobiliser on here?

In my opinion they are more trouble than they are worth.... I used a "Python" by Master Lock. Feed it through all 4 wheels then chassis the spare & lock it...
