RS 100 wiring problems

Hi Guys

I am sorry if this is covered else where on this forum, but i have just recently purchased a RS100 for a restoration project.

Trouble is that although i have now got it running well the electrics were shot.

After buying a new battery the electrics worked for about 30 minutes before packing up never to work again.

I have now completely rewired where necessary according to the haynes manual, but although my battery has power, as soon as i connect it to the rectifier it doesn't read any voltage. also the power isn't getting to the ignition.

The bike still runs but i have no lights or power to the rest of the bike.

Can anyone enlighten me as to what the issue could be?

I have left the original wires were i can and have checked that they are continuous with my multi meter

Any help would be appriciated.

Bike is a 1975 rs100 And i live in the Matlock area if anyone is willing to share their expertiese.

Thank you in advance

Gareth
