Guppy916 Posted June 10, 2023 Share Posted June 10, 2023 Hi guys I have just noticed that I have 14.5 volts at my Positive Terminal on the coil, could this be why I keep burning out coils, it's on a 1973 GT6 Mk3 Non Ballasted system Quote Link to comment Share on other sites More sharing options...
Howard Posted June 10, 2023 Share Posted June 10, 2023 With the engine running I presume? Quote Link to comment Share on other sites More sharing options...
glang Posted June 10, 2023 Share Posted June 10, 2023 Sounds reasonable as a running voltage doesnt it👍 Quote Link to comment Share on other sites More sharing options...
glang Posted June 10, 2023 Share Posted June 10, 2023 Oh and of course it should stay about that at all revs.... Quote Link to comment Share on other sites More sharing options...
Guppy916 Posted June 10, 2023 Author Share Posted June 10, 2023 Howard yes thats with the engine running on tick over with the volts ranging 13.5 to 15.25 ish Quote Link to comment Share on other sites More sharing options...
glang Posted June 10, 2023 Share Posted June 10, 2023 Hmmm thought it would be a bit more stable than that with an alternator... Need to see what it gets to at higher revs but with high system volts I always thought bulbs go first... Quote Link to comment Share on other sites More sharing options...
Guppy916 Posted June 12, 2023 Author Share Posted June 12, 2023 yes running a Rimmers alternator (17 ACR) 36 Amp part No GXE8211 all bulbs are Led's Quote Link to comment Share on other sites More sharing options...
glang Posted June 12, 2023 Share Posted June 12, 2023 Perhaps feel temperature of coil after next good run? Should be warm but not glowing😲 Quote Link to comment Share on other sites More sharing options...
Guppy916 Posted June 13, 2023 Author Share Posted June 13, 2023 Glang, after a 3-4 mile run around town, the volts have settled down around 13.8 - 14.5 from 800 to 3000 rpm, the coil is quite hot but you can hold onto it Quote Link to comment Share on other sites More sharing options...
glang Posted June 13, 2023 Share Posted June 13, 2023 Sounds reasonable so maybe youve just had bad luck? Im still on an original coil now 50+ years old🤞 Quote Link to comment Share on other sites More sharing options...
Guppy916 Posted June 13, 2023 Author Share Posted June 13, 2023 (edited) I hope so, my first coil after the rebuild only lasted 50 miles the second one about 75 miles then with alot of sorting I found that the company i used for my new loom sent a Ballasted loom, so i ran a new wire from the fuse box (the white one) so i now have 12volts at the coil, they were both so hot I almost lost skin when changing them. perhaps i'm just being paranoid now Edited June 13, 2023 by Guppy916 Quote Link to comment Share on other sites More sharing options...
