Wiring faults

[roverglenn]

Hi everyone
1969 V8 Coupe,no headlights on dipped due to a break in the wire from under the dashboard to the 2 fuses.I have run a new wire and it's all ok now however has anyone else had similar issues as I'm concerned other wires may also start to fail. Many thanks

50+ year old wiring will give trouble if not checked.

There are numerous bullet connectors which degrade if water gets too them particularly under the dash via a leaking screen.

On the P5B there is a bunch of cables inside the n/s A panel which are inline with water leaking via the screen surround rust holing under the rubber. The bunch is in the O/s A panel on P5s

The main battery heavy cable Lucars under the dash with the ammeter shunt are in line with screen leaks.  Older P5Bs and P5s have fabric coated cables which rot.
