Richeee Posted June 7, 2023 Report Share Posted June 7, 2023 Next couple of days fitting an acuspark electronic distributor. It will require a 12v supply. So cant just take a wire off the coil as ballasted. I understand i can use either a green wire for supply (the overdrive wire being close) which is fused or a white wire unfused. Must admit my preference is to fuse. As per the 3 i blew yesterday mucking about behind the dash. But obviously could leave me stranded if a fuse goes. Thoughts?

Pete Lewis Posted June 7, 2023 Report Share Posted June 7, 2023 it is most unusual to fuse ignition supplies a white would generally be ub fused ignition controlled circuits do not take the ballast as thats ony 6-8v not the 12v the accu needs to work over its voltage range so yes collect the 12v from a white the green will be fused ,not advised Pete Link to comment Share on other sites More sharing options...
GrahamB Posted June 7, 2023 Report Share Posted June 7, 2023 I too needed a 12v supply for the electronic ignition module as it is a ballasted system. I ran a separate wire from a switched unfused supply but fitted an in-line fuse holder. As this just supplies mA to power the electronics, I used a 3 amp fuse. The fuse holder is hidden behind the dashboard but is easily accessible from the driver's seat. When parking in a non secured location, it is easy to remove the fuse and push the holder back out of sight. Just remember to replace the fuse before trying to drive away or you will spend several frustrating minutes trying unsuccessfully to start the engine ! I have never had the fuse blow but I do carry a spare. Link to comment Share on other sites More sharing options...
Richeee Posted June 7, 2023 Author Report Share Posted June 7, 2023 Thank you for your quick replies . A white switched but unfused supply it is. The idea of an inline fuse i am mulling over. At least the ignition will still run if the green wires fuses go. Thanks Link to comment Share on other sites More sharing options...
