has anyone installed a calibre tacho before,when i rig up the ground and positive source i am suppose to get the complete light up of the tacho instead i get just one red light whats the go.?
thaNKS

if your talking about the illumination its a seprate power wire again, hook it too your parkers or ignition circuit if u want it lit up all the time

it says on the instruction to never connect the green wire which is the coil wire to a positive source why is that?

cos its actually recieves a ground signal everytime the points shut which is how the tach works

connect 12volts to that and watch the tach go up in smoke

,so do they have a fuse? because there is a possibility when trying to find positive source that the green cable touched.calibre is not an actual compnay i think super cheap make them,so i cant contact them.

bump..

stupid me did the same thing to an old VDO tach
wired it to the wrong side of the coil
no bang!, Poof sounds or anything
pulled the tach apart and found that i burned the coil
