The new Battery is in and it all appears to be running fine, The alt has a healthy output, but the thinking is the battery has a short onboard, they tested the voltage regulator and it also appears fine.
Why did the bike start? why did the bike run? Why did the voltage drop that much when everything said it shouldn't have, A lot of things have not made sense with this Termi kit, but it would appear that a light is now on at the end of the Tunnel.
I heard it this morning at the dealer and it was running well, much better than it ever has since the kit was fitted, it was running very rich though, so I said for them to keep it until monday rather than rush the job through on a saturday morning, and I'll keep enjoying the Hypermotard they have lent me
Pity I have to work all weekend
