Ok all the wise ones out there ...... i have a 75 series 1HZ 1996 cruiser ....
I am really hoping it has happened to someone else, we went for a day trip out to Old
Doomadgee Image Could Not Be Found and it was dark coming
home, all was normal until the last 10 klms and every now and then the lights would flicker over corrugations, i just hoped it was a bulb in the spotties but it got worse and we both noticed the horn was also beeping at the same time, it got even worse, only on corrugations so we stopped and lifted the bonnet, wriggled wires, checked battery terminals, wriggled the wires running up the steering coloum b ut could not get it to do it whilst parked with the lights on, we headed off and it did not do it again .........
I will be honest, i am really afraid of electricial shorts and any wiring i have done is fused at both ends, very
well insulated and secured
well ...
So PLEASE someone tell me it is common and exactly where i can find the problem ????? we are planning our hols and dont need this .... :-(
Cheers
Joe

Strange mate.
Been a while since i had my 75 series, so bit rusty on the wiring setup.
Did it flicker on high and low beam?
Best bet would be to look at a wiring schematic and suss out if those two circuits are in any way linked somewhere or share a connector, relay etc. Maybe they share an earth point or fusible link. Maybe even a connector under the steering wheel.
Thats where i would start. If nothing else was affected then it must be something that they share. Very hard to find though when its intermittent. But having the schematic and studying it will give you a good idea of what to
check and how things are wired, also be handy in the future if it happens again.

G'day Joe
The 75 Series Cruisers are a tad light in the wiring department so if by chance you have extra lighting "spot" lights and possibly higher wattage Hi ~ Lo ~ H4 headlight inserts, it can cause your vehicles symptoms.
Firstly
check the vehicles body earth cable as
well as the battery negative cable. Over time (years) corrosion build up destroys the earth path, the corrugations simply might have highlighted it all.
Also replace the Positive battery lead ~ fusible link as these also deteriorate with time/corrosion.
Check the wiring harness closely right back to the Solenoid on the starter motor, Toyota 75 Series are under wired in this department too.
Nice fish ;0)

Had a VF valiant, many years ago.
Strange things happened to it when the second earth strap was accidently left off..
Put indicators on at night, and the headlights would dim, and flash.
Horn would beep intermittently, ect ect ect..all instruments, except speedo would flick back and forward.
Suggest that you run a second Earth strap, this time, directly to the motor.
That trick also worked on my 2003 Navara, when she refused to start, even with the second battery, and heave duty jumper leads.
A short term fix might
well be to find where the earth from the battery connects, (in the Nissan's case, it's to a painted inner guard) remove it, and scratch the "living buggery" out of the bolt hole, and the surrounding paintwork, to give the connection a good earth
