I've jumped mine off a car battery with no ill effects but it's ill advised. I wouldn't risk it again myself.

Electrickery is the devils hand and stuff of legend but I think it's to do with the amount of amps a car battery can/will deliver.

Just a quick update, received the replacement igniter boxes today and bunged them in. I only turned the engine over briefly with the plugs earthed against the cylinder head and we have sparks, yippee!

It'll be the weekend before I can box it all up again, but things are looking good.

Thanks for all the replies, thing is I still haven't found out if there's a way to test the boxes, seems to me that they either work or they don't.

For future reference ...
I've bump started my 750 monster in the past and was surprised how easy it was.
And the reg/rec was already blown and the connector block had fried itself (didn't know that at the time).
I have also jump started it from a car battery with no ill effects, but the battery wasn't in the car at the time.

It won't damage it by jump starting from another battery, as you rightly say a 12v battery is a 12v battery regardless of how big it is.

It might be possible to do some harm if you jump start it from a running vehicle that has a higher output or 'dodgy' charging system?
