The Plus8 I had was fun for a couple of electrical gremlins. Rear foglight was flashing in daylight with no lights selected. Got the wiring dagram out after checks on the bulb and unit showed all looked ok. Traced back to a module behind the dash that cancelled the light when dip front mains switched off. The reset required to comply with regs. Opened it up as it rattled. The pcb was loose so glued back. Problem resurfaced a few months later. PCB still glued ok. Phoned Melvyn for a replacement.Factory order, no news, none in factory for the later cars. Checked the pcb under magnification, spotted a couple of not perfect solder joints. Quick dab with a soldering iron and no further problems. My fall-back was to buy a unit from Carbuildersolutions as a replacement.
Bullet connectors for headlamp wiring...no protection under the wing so they corroded badly and gave problems. Solid.cut them out and remade connections with added protection for new non bullet connections.
Move to the current ( no pun intended) 2023 Plus Four.....gauges failed after a few months. Sorted at dealer with a new pcb under warranty. The cause was a badly fitting connector to the pcb resulting in a wire failure. An assembly fault so the connection was compromised. Dealer got the new pcb from MMC next day and fitted. I was dreading a delay but pleasantly surprised at the speed.
Looking at the age of so many Morgans I'm not surprised that electrics give issues. A combination of design/assembly/age deterioration catches up. How long before system checking and overhaul becomes prudent?
