Somethings not right - battery related

well, thought id take my mind off of recent events and get a bit more done on the motor, anyway went down to the car once the little ones were all tucked in bed, connected the fuel lines, connected the coil packs and injectors, cas unit / TPS / ICV, O2 sensors, boost solenoids and what not, went to connect the battery, connected the earth first, went to connect the live and im getting arching like the 4th of july plus smoke from the negative wire, so removed the live instantly.

 

what would be the cause of this? im at a loss as the live is fed down to the start motor and connected at the correct points. the neg is also mounted on the gearbox mount bolt at the correct point. but seems like there is a short some where in the main loop. so what would be the main cause of fireworks at the positive / negative terminals on the battery when connecting?

 

problem is with recent events i cant even remember what or if I've missed a major earth point, which im sure is what the cause is, but would like a second opinion please.

Gave the engine a single crank from the key, didn't want to start it as still need to get oil in the gearbox and engine, plus get the coolant in, but it sounded good too hear it turn over.

 

Just got a few things to finish off, but once the fluids are in, should be able to at least start it and get the timing done. THE END IS IN SIGHT WOOOOHOOO!

was indeed, didn't notice when i bolted the wire on the first time around as the alt was still attached to the engine and was doing it fast as the engine was hanging over the car. so id basically created a live circuit straight back to the neg on the battery terminal soon as i connected it.

 

glad i had a spare alt in the garage now, that was lucky.

cant bloody wait lol, just cant get the engine oil at the moment, the past week in solicitors fees has killed me to be honest.

I've done exactly that before on another car after re-building an alternator, easily done mate, but a pain in the arse!

yep glad i took the time to take the alt off or i never would of known and would of still been wondering what was causing it.

 

So big thanks to Jeff for pointing me in the correct direction and also to you too tudor for saying about the diode pack in the alt which caused me to remove it and do a check.
