Cheers guys...I plan to get out there again tonight to check further...

Derek...I will try what you suggest and let you know the score...

I beginning to think it is a wiring/connection issue somewhere, as the wiring loom was removed during the winter when the bike was stripped. Perhaps I have unsettled a dodgey connection around the battery/reg wiring somewhere. Going to strip it all back tonight and start again.

Another thought. I almost forgot - check the earth to the regulator. There should be a short green wire with a solder tag connection to one of the regulator mounting bolts. Make sure it gets a good connection to bare metal. Any paint under it will prevent a connection. You should get continuity between the solder tag and the battery negative.

Wheeey...looks like I could be getting somewhere now.

Checked the reg red to bat pos and got very low (ie 1ohm) reading.

Striped all of the wires back checked all connections. One was dodge so replaced. Cleaned up the earth contact for the connector on the reg. Cleaned the contacts on the bat terminals. Replaced buller connectors on the yellow wires.

Started her up and he presto...13.5V across the bat:roll::sing:

Thanks for all of the advice guys...mucho appreciated.

Bring on the sun:smug:

After the horse has bolted but:
on the 906 paso there was a batch of dodgy earth connections with respect to the regulator. I believe the earth tab was on the wrong bolt or summat like that - anyhow, advice was to disconnect/reconnect the earth and make sure it has good solid connection with frame, and if necessary take separate earth from same connection to the battery.

on the 600 pantah, the sand cast casings gave a problem when the internal mould joints were not sufficiently ground off after casting. The extended joints encroached into the alternator housing just enough to cut through the winding after about 12 months.

Harv,
I've been on holiday for most of the last week so haven't kept up with what's happening. Good to hear that you got it sorted and that there was nothing seriuos wrong.

...and many thanks for your help with the problem.

Just can't believe you went away like that and left me alone to sort it...next time please OK all leave with me first:sing:

Thanks again.

Well you did get it sorted and must have learnt a bit in the process ;)
