ok its happend again....hooked up battery and within seconds there is a hissing noise near the "B" nut on the back of the alternator by "nut" i mean the tiny nut. and its started to glow yellow and get very freaking hot!! wires remined cool though. all I did for the BHG was take off the wiring loom from engien intake manifold and head.............................................. ................................................

I would check the wiring loom that you initially took off when you did your head, might be a good idea to remove them and check it then wire it back up again and try...

disconnect wires from the B nut and make sure none of the wires are earthed.

well I suspect its the alarm wiring causing it will have to check...all wiring I took from engine was put back into its right place ill grab a pic of the alternator back part tis burnt! mind you while this was happening the wiring going to alternator didnt get hot etc
