Beaver Posted September 29, 2008 Share Posted September 29, 2008 hey guys, just picked up a tacho for the hunter. its got 3 wires, red black and green and was just wondering if anyone could let me know which goes where? ive had a look around, and the best ive got is red goes to positive coil, green negative side, and balck ground. does this sound right? thought one of them would be lights...brand name is swoosh if that matters any ideas?

Raizer Posted September 29, 2008 Share Posted September 29, 2008 Red to any key switched +, coil + will work well if you don't want to find one in the car. And yeah green to coil - and black to ground. Normally they have a white wire for lights. Quote Link to comment Share on other sites More sharing options...

Beaver Posted September 29, 2008 Author Share Posted September 29, 2008 well it all goes and lights up when the keys are turned, does a sweet light up full rev swing at first which its aws lol. but it says that im reavving to 8500.....which it shouldnt be lol so yeh is trhere anything that i should check that causes this? would it mater if i got the wires on the coil around the wrong way? it also has a switch on the back with 3 settings, would this be 4, 6 , 8 cylinder? it has no markings Quote Link to comment Share on other sites More sharing options...
Requiemk Posted September 29, 2008 Share Posted September 29, 2008 yuh is most likely that switch adjust it, sorta obvious and something you try. your negative might be average to, recheck that. Quote Link to comment Share on other sites More sharing options...

Lump Posted September 29, 2008 Share Posted September 29, 2008 I put a tacho in a Triumph 2500 last year. It over read like yours is doing. I had to wire a diode into the the wire to the coil in order to cut down the other electrical impulses so it read correctly. I'm not that flash with electricity so the explaination above is a little hazy and I'm afraid I can't remember what rating the diode had. I'd grab a handful of diodes from Dick Smiths and have an experiment Quote Link to comment Share on other sites More sharing options...
