Hi Phil,
Wise words from Joe as always. I have found that on some cold mornings I get the "Parkbrake Fault" notice appearing, which I cured by disconnecting the battery for a short time, and then resetting everything.
I seem to have cured it by putting my battery on charge on a weekly basis as I don't do many long runs in the winter. I leave the battery connected while I charge it and did know about the vent tube ---- it is always useful to check it though.
My charger switches off when the battery is fully charged.
Regards,
Peter.
