Hi everyone,
In the rear of the RR is the plug which connects to a remote controlled unit a telestart t90 switch box of some kind, a telestart t91 fob is required to operate the unit. These fobs are a fortune on ebay as it has to be the earlier type which are quite hard to find, one went the other day for ÂŁ130 for the fob alone. For both bits of kit it could be between ÂŁ150.00 to ÂŁ200.00
It is basically 3 wires in the back of the vehicle as follows which would plug in to the remote unit
live feed
earth
relay on (supply out)
I have a GSM relay (ÂŁ17.00 Ebay) which i have already set up on my workbench, I have tested with the sms messages and I can switch on the relay for 30 mins etc which will communicate with the heater to run. The heater is setup within the vehicles ECU to run for a maximum of 30 mins to save starting power for the main battery.
As the GSM relay is permanently live it draws approx 50 to 100 mah all the time, I wanted to install a small 9ah battery I have which will power the gsm relay at all times. My RR battery is 950ah and I know you may think this would run the gsm unit for approx 5 months anyway before flattening the battery.
The RR electrics are such a pain in the bum if it doesn't have a fully charged battery, EAS suspension lights etc, ABS braking lights. hence my reason for the additional small battery. I only travel for a maximum of 15 mins each way to work.
I do not want the small battery to assist the large battery when the vehicle is starting though so the use of a diode i think, and I would like the vehicles electric to supply a controlled supply of power to the small battery to sort of trickle charge it at say 1-2amps when the vehicle is running and not at the full power available from the alternator which is rated up to 150amps I think.
is there such a single component that can deliver one way and trickle charge or a ready made component available that I am unaware of.
I hope that makes sense, I have a made a diagram as well which may not contain the correct technical terms but hope it helps. The drawing does not show any fuses however these will be included when I install the relay.
Thanks in advance for any help or guidance you may be able to offer.
