Hi All,
To extend on what Hap, Oudesluys, and Bob have already addressed, I would
suggest that consideration of the power path also be closely evaluated.
For example, my 64BJ8P1 has a lighting power path that extends from the
regulator through the light switch, on to the dipswitch, through a few
connectors to arrive at the light plug. Adding additional demand (increased
wattage headlights and/or driving lights) on the 45-year old switches and
through the original gauge harness and connectors will increase your chances
of NOT driving your Healey for long.
Reducing power through these components, while improving power delivery, is a
major reason why many have installed relays. This approach allows the current
demand on these original circuits to be substantially reduced to only that
needed to switch the relays. Further, higher gauge wiring is only necessary
in the new paths created from the battery, through relays, to the light
fixture plugs. Add strategically placed fusing and your electrical risk is
diminished while your lighting is greatly improved.
