Wiring

Hi guys im in need of a little more help, I've had a little look at the heaters I've adjusted the cables and everything and all is better than was but the Dan is on full continuous and all the wiring looks to have been fiddled with!
Can anybody tell me (simply) how they should wire up? pictures would be good also if possible, I'm going to try and rewire the whole heater from scratch, also how many resistors should there be for the heaters as there's only 1 with 2 wires? I don't understand how this can create 2 speeds?
Thanks in advance
Dan

The resistor path is one slow speed, the non resistor path is full chat.
On mine the earth wire fell off the inside of the dash switch, it still worked but was very poor, all the foam gaskets fail as well allowing what little air there is to escape!

Thanks a lot for that information on the resistor I assumed it would be somewhat like the newer kind with 2 different winding but seems as there is only 2 speeds what you say makes a hell of a lot of sense now!
Thanks for the reply hopefully I'll be able to sort it out now!

That link is excellent thanks again
