Hercolor Digital Dashboard on GL1100

Here are the total instructions that you get when you buy one of these units.

Orange wire to left turn signal light
Light Blue wire to right turn signal light
Blue wire to the highlight Indictor
Blue/White wire to the water temperature sensor
Yellow/White wire to the oil float sensor
Black/Yellow "Wire to the engine pulse,
or the positive of the Ignition coil"
Red "wire to the power positive, before the ignition switch
Or directly wire on the positive of the battery.
Make sure the power always on"
Green wire to the power negative
Black "Wire to the ignition switch positive
or the oil gauge 12V positive"
Green/Yellow Wire to the brake (either handle bar switch or the foot brake switch)

1 The left button is turn of the single mile and total mile.
2. The right button is the turn or oil volume and the water temperature.
3. When you want to set the time, please press the left button first, when you see the screen shows "odo", then keep press the right one about 5 seconds. Then you will see the set part sparkly. And then the left button can choose the hour and minute and the right button can set the time. Then press the right button again for 5 second. The the time set is complete.

Here are some pics of the installation so far.

This pic shows the wiring mess. The relay you can see is for the neutral light. The 9 pin connector just below the relay is the connector that the original dash plugged into. I have a mating connector on it to patch across to the new unit. The white 9 pin connector to the right is the connector on the end of the new unit's wiring harness. It is a perfect match for the original 9 pin connector for the original dashboard. I was lucky enough to find a couple matching 9 pin connectors at a junk shop down the street. It sure made things easier. The wire colors don't match, but it isn't hard to figure out what is going where.



This next pic shows how I have it mounted.



Next shows the Red "P" and the High Beam indicator.



The next one shows the left turn signal and "neutral" light.



This one shows the "neutral" light and right turn indicator.



Ok, I now have a speedometer! I made the bracket for the sensor, mounted the magnetized bolt and it works. At least it works up to about 6 mph. That's what I got out of it spinning the front wheel.





Friday, I'll get the rest of the bike put back together and take it for a ride. My next project is to install a Rostra cruise control. I won't be able to work on it tomorrow, Wed, and Thur. I work tomorrow, and immediately after work I'm going to Rogers, AR to dog sit/house sit for my brother while he gets some medical stuff done in Little Rock. Then I work again Thursday.

If anyone has any questions on this setup feel free to ask. It was easier than I originally thought it would be.

Here are the results I see after about 60 miles of riding. It was a very bright day, and the turn signal lights are very dim. You have to look close to see if they're flashing or not. The other indicators are ok, not real big but noticeable. When riding into the sun it's hard to read the speedo, but that's to be expected. The tach reads a bit lower than the mechanical tach did. I don't know which is right. At 60 mph, it's reading about 3200 rpm. The speedo is about 5% high, but that could be my measurement of the circumference of the front tire. The temp gage seems to be working fine, but the gas gage hasn't moved at all yet, so don't know how that's going to work out. The speedo was checked with my street pilot gps. The odo and trip meter seem to work fine. I'm still not sure how to reset the trip meter. I'm thinking some kind of shade will help on the readability. That's what I use on the gps, and it helps a lot. I might try tilting the unit up some more and rigging the shade for the mechanical gages to shield this unit. I will probably keep this unit as I'm tired of replacing speedos and tachs. I hope the gas gage proves out to be at least somewhat useful. Whether or not I buy another one for my 76 remains to be seen or not.

More progress on the unit. I punched holes eliminating the film aver the leds for the turn signals. They're brighter in the shop. Hopefully there is improvement out on the road. I disconnected the neutral light and connected the oil pressure sensor to the brake light. It works nice. I bought a dash light and hooked it up under the unit for a neutral light. Couldn't find a green one, so it's red for now. The gas gauge still isn't reading anything but full. I bought a pot to try, but don't know if it's enough or not. The tank is full and we've had a couple days rain, snow and cold. According to the seller, the gauge is looking for 510 ohms. If so, I will have to get some more resisters.

I started installing a Rostra Universal Cruise Control unit yesterday. The unit is now mounted. It's behind the right saddlebag just to the rear of the shock. I hope to get it wired today. More to come.
