The fact that the two heating elements are separate on the front screen is a very useful feature in my opinion.
The two elements can be connected in parallel for initial defrosting and then with a bit of switchery can be connected in series with effectively half the total initial power for demisting during driving. Or 1/4 per segment.
Is there a figure for the d.c. resistance of each half please ?
How are the connections made ?
Thanks,
Tony.

A heated front screen will probably draw 20 amps or so. Typically switched on straight after start-up on a cold morning, when the battery is taking maximum charge. Plus rear screen current draw. I think a Lucas 17acr was rated at 36 amps max output....

Hi, I now have new front laminated front screens available, green, clear and heated,
I can also arrange delivery uk and abroard.
If you are interested, contact me with your needs,
Thanks, Robbo.
So how much are they and what wiring modifications would be needed to enable the use of a heated front screen ?
I was thinking about using a timer relay,like the idea about having heated front screen

Dave


Hi Dave, Clear is £206.00,,, Green is £216.00,,, and Clear Heated is £306.00, They are wired in two halfs, and are best switched through relays, no over complicated wiring necessary, (Tony g) is correct, if i can help any further I'm on 07801480007.

Whats wrong with using just a switch like the rear one has?

Tony
The rear one is surface mounted, so it matters not how long it is on for. The front ones are embedded, so to prevent overheating they need either a timer or a thermostat.
Hi, The Heated front screen does not need a timer switch, they dont get overheated, just swich it on when u need it and of when its done its job,
They are the same make as BTCC cars use, so well tried and tested.
Any worries, just call me on 07801480007, thanks, Robbo.
