installing Tachometer?

[clarion]

i got a tenzo R tach and i just want to hook it up to see if it even works, it has a red, black, and green, and 2 yellow wires, anybody knows how to hook it up

I don't know specifically, but to help aim you in the right direction, I beleive you will need Power, Ground, Power for lights (red, black, green) - and signal... signal for tachs is usually off the alternator.

Should be (but you may want to check) Black to good ground, Red to switched/fused power feed, on tachs I've installed Green goes to ignition coil, Now with 2 yellows that sounds strange but you may need a seperate power and ground to your light, or you have 2 different lights in the tach.

I'd just use some jumpers from the battery put your black to neg and swipe each yellow line to the pos. The light should go on and off.

unless that tach is specifically made to work with waste spark ignition systems, it will register double the rpm as what the engine is really turning at.

To resolve this, you can either purchase an MSD tach adapter, or a similar item from a guage manufacturer.

In my case, I have an MSD digital ignition system and it has a standard tach output on the side... so i can hook up any tach I want.. :)

LOL

and signal... signal for tachs is usually off the alternator.

I'm confused, how would you get a tach output off of the alternator?

ill sell you my tach adopter, its a autometer (yes you need it)

[evan938]

is there somethign wrong w/ your stock tach?

[tricked03gls]

i used it for my shiftlight which had a tach basically built in to it

[clarion]

nothings wrong with my stock tach just want to see if it works, but it would look good in my car, the numbers has a nice blue color to them, it match perfectly in my car

how much do you want for the tach adopter?
