hey all, im new to this. i bought a stunning xj750 september of 05, and recently i had a battery leak onto the solenoid and the associated wires. now, when i turn the key and switch to on, before i even hit the start button the tacho goes up and down between 0 and about 3000rpm, with the engine completely off. has anybody expeienced anything like this? any help would b appreciated. cheers
