Hi Guys,
Well I have my first problem with my EFI Bulldog bike. Once while I was riding a month ago the engine just died. If I pressed the ON button and START the bike would restart while coasting. And then after I parked the bike in the garage after an all day ride, I went back out to check the trip mileage and when I turned on the key the speedo needle started to climb to reset but all stopped dead. No headlight no nothin! I turned off the key and on again, but all dead. I checked the EHC LEDs and when I would turn on the ignition switch it looked like almost ALL of the LEDs would come on except the GREEN. I gave up trying the switch so I accepted something had happened. About a half hour of cool down I tried the ignition switch again and this time the speedo reset and the engine would start - several times. Don't recall if the bike was riden since weather and all.
Well this Sunday it happed again while out on a group ride 50 miles from home. We stopped for fuel and when I tried to start-up, the bike was dead, same as before. I pushed it to the bar parking lot next door and began checking. Removed battery (+) cables to try EHC reset - no luck. All the same observations as the earlier incident. I decided to wait for a cool down again and grab a beer. When I returned to try it again - IT WORKED! Ignition ON speedo resets with LED idiot lights - hit RUN - START - let's head for home!
I have nothing heavy on the key ring. It's getting power to the EHC when the IGN switch turns on.
Circuit breaker fault - weak low current contact by heat?
Could the IGN SW be affected internally by engine heat?
Could it be and intermittent EHC or heat related EHC?
Wiring - seems more heat related at this point, but a weak connection at temp could be causing EHC startup checks to fail.
Can the EHC be accessed by the BDM PC program even when it won't come up? I'll talk to Beezer.
My bike is at BigdogBro2's garage and I plan to try it again after work.
Yes it's under warranty.
I'm electronics and mechanically savy and understand diagnostics.
Any experienced input would be appreciated.
Thanks!
Rob
UPDATE: 9/1/09
Replaced the IGN switch but no improvement. The old one was very sloppy on the detent clicks.
The harness connectors under the right side battery cover may have a loose wire or bad connection.
I'm checking into the IAC (Idle Air Controller) on the throttle body may be a cause. related?
The EHC now comes up and the speedo resets since checking the connectors.
Placed dielectric grease in all the connectors on the right side cover.
I didn't tie-wrap the cables and connectors as tight as before thinking the stress was pulling too much on the connectors.
