Mystery high current device.
Posted: Mon Jun 19, 2017 5:07 pm
While sorting out some speaker wires behind the left hand panel, I noticed after all this time (43 years ? ) that there was a mystery electrical object mounted in the main fat battery cable with the terminals covered with insulation tape.
It didn't seem to be doing anything useful there so (after disconnecting the battery in the boot) I took it out and bolted the resulting two ends of the battery cable together and taped them up.
The operating handle was evidently on a fine stem and has broken off, so I cant really tell if it was a push-pull switch or a rotary one. I tried both actions using an ohm meter and the two fat terminals seem to be always connected and the other terminal never connected.
Has anyone seen one like this before?
It is maybe a relic of when Malcolm Ricketts owned the car for its first year and did some hill climbing events (I think). Perhaps it was a batter isolation switch and the handle broke off.
The small terminal is labelled C-B, the large copper one near it is labelled B and the other fat one is labelled E. It appears to be made by LUCAS, but I cannot make out the part number. There is a number which might be 76605B4482
