Late speedo wiring

[kessey]

Heres the trouble like an idiot i discounted my speedo on my 69 minor and carnt remember were all the wires go and to make it worse i have my lost the use of my wipers.

i was trying to rectify a god awful noise coming from the speedo which i manged to sort with some WD40 and cleaning the end of the speedo cable. NOW ive got to put it back together and sort the wipers

can anyone help a picture and some advice would be very appreciated

See the excellent wiring diagram at the top of this section. Print it off and laminate it if you can - and keep a copy in the car.

The wipers are not working because you have disconnected the green wires from the B terminal on the voltage stabiliser on the back of the speedo.
Blue/White wire warning light to Blue light left side of speedo
Green/Yellow wire warning light to Amber light left side of speedo
Green/Brown wire warning light to Amber light right side of speedo
Brown/Yellow-White wire warning light to Red light right side of speedo
Red/White wire panel lights in two remaining holes

[kessey]

Theres a spade connection with two green wires from it. A green/yellow wire, green/purple wire and finally a green wire that is only connected on the speedo

[mike.perry]

On the back of the speedo there is a voltage stabilizer at the top with 3 green wires to the input B terminal which acts as a junction box, and one light green wire from the output I terminal to the fuel gauge at the bottom of the speedo. A green/brown wire connects the other terminal on the fuel gauge to the fuel tank.
The only green/purple wires should be from the brake light switch to the brake lights

PROBLEM solved was more trail and error for me but eventually got there alot of bulbs I need to replace. Personally found the diagram useless but thank you for letting me no where the bulbs fit correctly that was a lot of help.

BIG thanks goes out to both of you very much appreciated

The diagram is completely obvious - it's a simplified version of the original, nicely colour coded and laid out by Barry . Well worth studying it and learning how it all works....... Invaluable in a break-down situation.

Looking back I should of equiped myself with some electrical tape would of saved myself a lot of time but atleast she's sorted now. Looking forward to the Birmingham branch rally to webbs.

I see now on the diagram should of studied it better on my part. Sorry for any offence caused I'm just more of a hands on guy electricals bot my speciality I want to fit a radio but worried about draining the battery power. Car is still running dynamo

[bmcecosse]

Unless you are planning to transmit to the World - the dynamo will manage ok........ But of course, most wireless sets these days are -ve earth, so your car will need to be converted if not done so already.....

[kessey]

I think it may have already been converted as it has an ariel already on the car but I don't no what radio was in it before. I don't plan on putting a CB in or anything like that just a nice simple cd Player

[bmcecosse]

Just check which terminal of the battery is connected to the body of the car - it needs to be the -ve terminal.

[kessey]

Battery Negative to earth

Then a modern radio will fit no problem. Its negative earth.
