mouse 6 Posted May 2, 2015 Hi Gang. I am rewiring my 1965 Tina mk.1 and I wan't some way of cutting the battery power lead off in case of a problem. I was thinking of a starter solenoid but wondered if it will take a continuous load. It won't be taking the full starter load except on starting. This is just a precaution in case I wire something up wrong-I don't want a fire at this stage of the rebuild.. Regards Mouse.. Quote Share this post Link to post Share on other sites
Danish 294 Posted May 2, 2015 AN FIA approved kill switch would be the best option - the red ones you see in rally cars. They are more than just a big switch, mine has three separate circuits and disconnects the ignition, shorts out the alternator and isolates the battery at the same time.

Hi Thank's for your prompt reply, I did not think there as was a purpose made item. Regards Mouse.. Quote Share this post Link to post Share on other sites

Regards Mouse.. you can get high current inline fuses, if a wire shorts enough to cause a fire the fuse will blow. i fitted one on mine as i nearly had a fire, on mk3s at least, theres a potential fire starter. it comes in the form of the headlamp relay. the live feed comes straight from battery, the circuit board on base of relay can fall out, shorting the battery straight to earth, this happened to me and melted my loom. had to rewire it all again. so i fitted a 30a fuse and hid it under battery tray this covered everythign except starter feed. starter feed would need 60a fuse, handy if the main starter feed cable comes off the solenoid and touches Quote Share this post Link to post Share on other sites
Danish 294 Posted May 3, 2015 you can get high current inline fuses, if a wire shorts enough to cause a fire the fuse will blow. I've fitted a 'mega fuse' to my Mk3 which protects everything except the alternator and starter wiring. I originally fitted it beside the nearside headlamp, but decided that would be a %&$£@* to change on a dark rainy night, so I've since moved it closer to the front.

Danish 294 Posted May 3, 2015 wouldnt 175amp be enough current for a fire? I should think so. They come in 40, 60, 80 and so on up to 500 amp. I've been testing with a 40, but I'll have to calculate the actual value I need - whatever the car consumes when everything is switched on. Quote Share this post Link to post Share on other sites
