The dealer wanted $35 plus tax and a 2-3 week wait.
I went across the street to shucks and bought a 12v relay for $2.29 and it works JUST FINE!!!
(worth a try?)
 
well i have 2 buddies with the same sled and i tried both of their relays in my sled and they still didnt work. ive been through everything on the sled. :frusty:
 
here's a weird one. Tryed another new relay in my sled and got the same result. no tack. still have the tack with the relay that is on my sled. Why would a new relay not give power to the tack?
 
i never had any luck witht he napa ones. i tried one, took it back and tried another one still no power to anything. not sure how people are getting these napa ones to work.
 
the one i'm running now is a napa from 2 years ago. the new one's have gold plug connectors. the old one is silver, just a way to identify them. got it figured out though. Napa gave me AR274, the wrong relay. got the correct one. AR201. works fine.

ive tried that in a way. i have an mxz that i turned into a summit, and it has the separate spedo and tach, and i tried my buddies tach off a 06 rev x package and it still didnt work. could be because we have different set ups.
 
Seems like I had this problem and on my new relay I just moved the wire in the plug to the relay port that wasnt being used and then everything came back on. Been fine for 3 years now.
