Big Dog Motorcycles EHC RIP Kit Torture Tests
Scroll down for all videos and technical information below videos.
Big Dog Motorcycles are known for being built with premium parts that deliver the highest performance available anywhere in the American V-Twin class. Like many high-performance machines, the environments in which these parts must survive can be extremely violent.
Big Dog Motorcycles’ Engineering Division developed a special department dedicated entirely to measuring these environments and engineering parts to withstand them. The findings of this Department confirmed what the warranty department was seeing…The service life of the main computer on the 2003-2011 Big Dog Motorcycles is the “weak link” in an otherwise robust chain.
Most Big Dog Owners cringe when they hear the three simple letters: E.H.C. “EHC” stands for “Electronic Harness Controller.” This computer supplies power to all the different systems on the motorcycle. Originally designed by aircraft engineers, the EHC is a magnificent design in theory but the physical application was a different story.
The theory was to produce a computer that uses low-current circuits and internal fuses (known as “fets”) to eliminate much of the bulk associated with the conventional electrical system options at the time.
The EHC computer also employed multiple safety and theft-prevention features that helped protect both the owners of the motorcycles, and the manufacturing company.
The EHC computers were put through many hours and miles of testing before ever being implemented into the production motorcycles for the 2004 model-year. However, nobody can test a motorcycle’s durability like the American Consumer and when the warranty claims started showing an increasing number in EHC failures, Big Dog recognized there was a problem.
After many revisions to the original design without success, Big Dog finally aborted the EHC program for a fuse-and-relay design called the “PDM Kit” short for “Power Distribution Module.”
This system was also plagued with failures as it still requires the use of a solid-state computer to allow functionality of the momentary hand control buttons.
A couple other aftermarket wiring companies came and went but only had marginal success because the systems were complicated and required much labor and modification to the bike’s original harnesses.
It wasn’t until a group of Big Dog Factory veterans decided to fix the problem once and for all and developed a lasting solution…Known today as the EHC R.I.P kit. The design strategy was simple:
Here are our findings:
As mentioned above, nobody can test a product like the American Consumer. We have been selling this computer system (EHC RIP Kit) for over 3-years and with hundreds of these on the road.
It is also the same system we use on the new 2016 production Big Dog Motorcycles. Not a single computer has failed at the time of this writing. There were some early failures from mis-pinning harnesses at the factory that have caused less than a handful of failures to date.
Mis-pinning failures have since been eliminated by employing a third-party company to test each harness before it ships out the door. Please don’t be fooled by our competitors’ copies and claims. Their only attempt to compete with us is to publish false information and post bad reviews online under fictitious names. I can guarantee they do not have the quality control or even the proper equipment to compete at our level.
We don’t get into the “mudslinging.” We beat our competition the good ‘ol fashioned way be offering the highest-quality product, fastest lead-time, and unmatched product support.
