I need some help please. I have a 41 year old Italian sports car, as per all Italian cars of this age the electrics are woeful! The resistance of all the wires and connectors has increased meaning that there is rarely 12v where it is needed. For instance the electric/power windows only have between 8 and 10v at the motor.. and this is a real issue as the windows barely raise or lower. Like all owners I have changed all that is possible, upgrading fuse boxes, relays and so on.
The power window motor has 2 wires and depending which one is +ve the window goes up or down. The motor drives a worm drive, which in turn drives a cable winch which pull up, or pushes down the glass. It is possible to buy power boosters, but as with everything else on my car, I want to do it myself.
Both power windows are protected with a single 10 amp fuse so I guess the maximum drain can be no more than 5 amps each, as the windows an be used together.
I have seen many 12v 10 amp boosters on ebay, but I am not sure how I could cater for the switching +ve supply.
Can you help me please?
