Electrics gone haywire ! Options

[63acornwall]

Yesterday was like a normal day . I started up my 914/6 Tribute ( original 1975 914 with a 1974 911 6 cylinder transplant running on Webers ) , ran down to the fuel station in daylight , turn indicators work fine . Came home and discovered that ;

horn does not work
clock does not work
sidelights do not work
headlights do not emerge ( but high beam indicator light does)
hazard lights do not work
windscreen wipers do not work

What does work is ignition light , starter , and turn indicators

Had a look at the fusebox which is aftermarket with blade type fuses , random checked a few fuses eg headlamp motor , parking lights - all ok

So I guess there is no power supply to those circuits into the fuse box if fuses OK

All I can think of is that some multi lead part of wiring harness has come unfixed but where do I look , I dont fancy pulling spaghetti out in case car ceases to work altogether !!

Advice please - my specialist is 80 miles away but will drive it there as a last resort

Generally the hazard light circuit is one of the most robust and least encumbered, ditto the horn, at least in cars as old that this one. Seems like time to dig out your multimeter. Since no fuses are blown, the break in the circuit is possibly up stream of the power block vs downstream. Hard to tell how far your feeds differ from the norm given the engine swap but a quick Google of 914 wiring schematic will turn up the originals which is probably where you should start.
