I got that Cobra 01-1637 Tachometer and tried to install it but one of the quick-slide connecters was broken so I called cobra and they sent me new connectors.
I had already installed the Tach before realizing the one connecter was bad and it was the Coil connection that had to wait for the new connecter. I had used the cracked broken connecter with electrical tape thinking I would replace it when the news one came in. The Tack was acting funny, only going to 1.5 1000 rpm and fluctuating, I thought it was that bad connecter.
New connecters came, I installed it and by then the Tach was completely Dead. It lighted up but the nedle had ZERO movement even before I installed the new connecter, and afterwards. It had fluctualted like I said but after a few days went dead and the new connector didnt help.
I had bought the Cobra Tach "New" on ebay for less than 1/2 price ($130) and when I got it I noticed the install instructions had fingerprints on them and they looked used, the box looked like it had been opened a few donzen times too, but I guess I was in denial and believed it was New.
I ended up returning the Tachometer and got my money back. I now believe the Tach was actually a defective return that found its way back into the sales area of an internet parts dealer, in fact, the dealer told me it has happened before where he sold someone and exhaust system and the customer found someones Old exhaust in the box when he recieved it.... Arrrrghhh see what I get for trying to save a Buck!
The old addage, if it looks too good to be true, it probably is..definetely applied here.
I left the connectors attached to the connection points on my bike and ordered some matching male connectors and also orderd a Brand New Tach which is due in today,
shoulf be an east plug and play deal, I hope it works.
To be continued.....
