Help needed

went to start her today but nothing one of wire on ign barrell tends to come off so undid inst panel sily, me didnt disconnet batttery whoops spark from a wire on barrell now nothing at all? i have a alternator and wires going to voltage reg do i need the reg?????????? and she still not starting, there is power going into voltage reg, there is no power to fuse box. No lights exterier or on dash, no ancillaries have any power.
Crossed solenoid and starter is working so power to that. any ideas folks pleeeeaaaaaaaseeeeeeeeeeeeeeeeeeeee???????????

Alternator etc should have no effect on it trying to start ( cos your batteries not flat is it ) assume it a series with no computers! Not really my area but generally when you do that you blow something, a fuse! A fusible link. Melt a wire. Check the basics first. Most cars have a really big fuse to protect the main circuits, I'd be looking for that first

Not really sure why you got a voltage regulater if you have an alternator
Thought when you convert from dynamo you take that all out
Striking a live wire to earth should only blow a fuse on a series cos there is nothing computerised to blow
Like already been said start with the basics
