Morris Minor Owners Club

Can someone tell me what current a saloon heated rear window draws? I intend fitting one and AES electrical sell a 20A 10 minute timer relay which sounds like a good idea -anyone fitted one of these? I also want to install the wiring in advance of getting the screen fitted by Charles Ware, so need to know what to install. Thanks.

Someone called Alec on here wrote this:

"I have been watching this thread and finally got round to doing a current measurement on my wife's Traveller's heated rear screen (Obtained from the Morris Minor Centre, B'ham). It draws 6 amps, so a load of 72 watts nominal.
If a switch of sufficient capacity is fitted then there is no real need for a relay. Switches are commonly rated at 10 amps with many rated for 20 amps. 14\0.30mm (1sqmm) cable is rated at nearly 9 amps but it would be better to use 28\0.30mm (2sqmm) cable to minimise voltage drop and so give more power at the rear screen."

I'm guessing similar would apply to a saloon HRW.

Thanks, I've seen posts about traveller heated screens, but wonder if saloon screens draw more current being a different shape and size?

There may be a slight difference, but not as much to make it appreciable in terms of the type of switch/relay/cable you need to wire them in.
