Instructions on when and how to use the Auxiliary Tach Lead

Q: When & how do I use the Auxiliary Tach Lead?

A: ONLY use this auxiliary lead if you are experiencing tach or needle bounce, after the REV-N-NATOR is installed. If you have no tach bounce, don’t use the auxiliary lead!

In rare cases of having "Tach or needle Bounce", you have the option to use the auxiliary tach lead, located on the reverse side of your REV-N-NATOR I.C.U. "Grey wire".

When using the tach lead, unlike the braided ground, you will need to raise your REV-N-NATOR box up off firewall slightly, using just some small washers. The tach lead should not be pinched.

Do NOT "notch” or cut into box, as this VOIDS your warranty for a replacement or refund!

Q. How do I connect the auxiliary tach lead, if I need to use it, to correct my tach bounce?

A: Remove your negative tach lead wire from coil and connect the negative tach lead wire DIRECTLY to our auxiliary tach lead, on back of box. (grey wire) DO NOT SPLICE in original tach lead wire with it still connected to coil OR CONNECT TO NEGATIVE ON COIL! This can damage your REV-N-NATOR!

WARNING: IF YOU SHORT OUT YOUR TACH OR THE NEGATIVE WIRE ON YOUR COIL, IT CAN DAMAGE THE 'COIL DRIVER' IN THE REV-N-NATOR! THIS IS NOT WARRANTIED, HOWEVER, IT CAN BE REPAIRED FOR A FEE.

Please let us know if you have any questions on the correct way to set up using this auxiliary tach lead, as we do not warranty, if you do not do so.
