EHC for 2003 Big Dog

This EHC replacement controlls the functions of your Big Dog bike. The EHC 03 is made as "Plug & Play" control boxes for a fast change (about 3 minutes) against the old device. There is no need to spend some hours for cablework, stripping etc...

Some changes compare to the original EHC provide a better performance and lifetime.

The following functions are implemented:

- Flasher control

- Auto flasher off function, emergency flasher

- Control of low - and high beam.

- Control of starter solenid

- Brake light control include modulation

The outputs of the EHC 03 are short circuit protected and self resetting when a short circuit is not present anymore. However, we recommend to put a 20 amp fuse in the main line between the battery and the EHC.High temperatures on the board due to a short circuit in the harness or somewhere else at the bike result in small gaps in the epoxy material what result that the EHC is not waterprooved anymore.

Some functions are user programmable and can be changed at every time. Just press the horn button while turn on the ignition switch and your are in the "program" mode. A one time emergancy flash will indicate the program mode. A press on the right or left indicator button will switch on or off a small showflasher function. A press on the horn button will switch to the second program option. So, you can easily adjust your own settings with 6 simple steps. For further infos, just feel free to take a look to the manual (pdf).
