I have a 1971 US Tr6 running on twin Strombergs.
I have had poor running usually when hot and the car loses power.
Initially I suspected fuel starvation and ended up swapping the tank and replacing the fuel lines and fuel pump as the car has sat for a few years prior to my ownership and tank was rusty and blocking fuel filter etc. (needed doing anyway)
Thought this would cure the drop in power
Car still starts fine and seems ok until under load and then it starts to die and the ignition light now comes on either periodically or continually. Checked battery and its reading 12V off and 13.5V at idol.
Changed the king HT lead and things improved somewhat but after about 2 miles the light started again and power lost.
I have now changed the coil and HT leads and still it persists. I now strongly suspect the alternator.
I want to change the alternator and have a couple I could try but the wiring is different to that on the car.
The 2 I have use a block with 3 connections and is held in place with a little metal clip.
On the car there are 5 connections.
Thick brown and white wire
brown and white and yellow and white together
single brown and yellow.
Question is how do I wire the newer alternator to this arrangement.
Any help much appreciated. Its driving me mad.
