This is just the start of what will probably be a very long post…
My bike cut out several times recently in mid-driving. The symptoms (wet weather, sudden cut-out, restart after bike cooled down, etc.) all seem to point in the direction of the HES – Hall Effect Sensor (ignition transmitter). Also, I’ve no idea if the sensor on the bike is original or not. By all accounts, it’s a good thing to replace at some point regardless.
Apparently it’s easy enough to do yourself, so I’m going to give it a shot.
The first challenge is to determine whether you’ve got the early type flat-six connector or the later type.
The advice I got was “The easiest way of telling for you is to look at the multi-plug from the sensor, the early type is like plug A in the diagram, the later one is like plug B.”
Which means… yup! you guessed it… remove the fuel tank (arghhhh!). Actually, it’s not that bad – it’s more of a mental block. I had the tank off in about 20 mins.
I identified the multi-plug by tracing the wires up from the sensor behind the alternator pulley cover and comparing with the diagram. It was located right in the center of the bike next to the Motronic unit. I have the B (later) type (my bike is a 2001 so I’m not sure what constitutes “early” or “later”):
This is as far as I’ve got for now.
I’ve ordered a replacement part so as soon as it arrives I’ll start on the removal and installation (fun, fun, fun!)….
oh nooooooo.
Yup! I was thinking of you
