Totally frustrated and feel I'm getting the run around. I feel I might have made a bad decission and should have gone to another manuafacturer.

I like the idea from the previous commentor that he made his own controller. If possible list what you used. This maybe the way to eliminate my problem but I feel Show Chrome should stand behind their product and I would rather keep the product original.

First off installation was not a problem. Crips went on and wiring is simple. Years ago I went with and additional fuse block that accomendates all the neat stuff you can add to your wing.

Well go figure no heat and then I saw the NOTE about the voltage has to be at a specific voltage. I checked and the voltage is below the manuafactures limits.
Decided to attached the hot lead directly to the battery. All I get is the 5 blue flashes which indicates voltage below the limit but I varified 13.4 to 13.7 of the battery. So there is no voltage drop there.
I checked the continuity for both LH and RH grips and they are good. Power to the controller is reading 13.4.
I believe the controller itself is defective.
Made a call to Show Chrome, explained the problem and the rep agreed most likely the controller was defective. Asked for a replacement part but I had work this problem thru the vendor. I returned the item to shop wear I purchase them but still waiting on a decission. I sure would like to see some feed back from the commentor that made his own controller.

This is an update from my previous post. After removing the controller and replacing it with a switch and a few other modifications to replace the controller they work great. They take a bit to get warm but full on they will probably burn you. I decided to not send these back because I didn't want to have to tear into my bike again just to be without grips for a little while. I'm sure that wingstuff or show chrome would have replaced them had I asked. They came with an extra wire that would go from the accessory block to the controller if needed, but they plug right into a 04 GL1800 without any problems. Over all, I would recommend these to anyone on a budget that wants to ride in the cooler weather.

I love these things. they are so good. I have had mine for 2 years now with no problems.

Cheap. Worked for a couple of weeks, then the left one barely gets warm. I will spring for Honda OEM grips.

Installation wasn't too bad, but I installed these just prior to a seven day ride into chilly weather - and they didn't work. Lights came on real pretty on the controller, but no heat. Called Showchrome and they couldn't really help diagnose a problem. Recommended I return them for a refund. Been trying to get a return authorization from Wingstuff for a week without success.

I'm thinking I'll just plunk down the extra money and get a set of Honda heated grips. Way more expensive, but I bet they'll work and last a long time. Don't have a lot of spare time - prefer to spend it riding vs. troubleshooting electronics.
