Title: My Bedford Wiring Is A Disgrace!
Post by: Hashman on August 06, 2009, 11:01:58 PM
Trying to get the beddie roadworthy and it seems to be one thing after another!  Just got a new 2" exhaust system to also find out the mainfold gasket is also gone.  Windscreen wipers seem to have two settings but just the ONE SLOW speed and now I keep losing different headlights when it feels like it.

Wiring or switches ya reckon?  Hi beam works well but the normal beam works intermittantly.  The wipers someone reckons its just the switch but i got a 2nd hand motor just incase.

Anyone know a good auto elec in eastern suburbs of melb or should i give this a go myself?  Any ideas of which things to try 1st and how?

thanks for any input

dave

spray some CRC into the back of the switches, sounds like dirty connections.

take the plugs out where they join the firewall and clean the frak out of the contact blocks youll find things working you never new you had. 8) :o

go round and do as many earths as you can

there is a good contact spray available just for this but its about $30 a can but well worth it , it is from the crc range blue and white can I think. :P

wiring is always a nightmare. in fact  i have a desire to spend some time with an auto electrician to find out how he thinks.

last electrician i took a wiring mess to he got really nervous and ran away. bedfords:)

Hey Dave

Give it a go yourself. it's not to hard if you have an understanding of the basics, you just tneed to be thorough, persistant and patient.

Get yourself a wiring diagram, multimeter and a 4 meter length of insulated wire with aligator clips on each end.

Wiring diagrams can look confusing, but if you isolate one thing, and then follow it through you will soon see how it works, spend a lot of time following each of the individual elements, doing this will help you understand all the circuits and recognise the wire colours, switches etc. Do this research befor you even touch the tools.

Having touble understanding it all, break it down, for any circuit to work electrons have to flow from the positive post of the battery through a cable to the device and then through to the negative terminal of the battery. This can be done all with wire, but to save on wire they use the metal body as the return path to the battery.

Mmm this is getting bigger than I planned....I've been thinking of penning a tech artical on electrics - time to do it.

I will PM you my number

Warren

disconect the battery pull out all your fuses and clean the fuse box contacts with a bit of wet n dry clean the fuses to and you will find its a murkle!!! ;D ;D it worked great for me

Wow thanks guys for the help!  So far all ive had time for was remove the plugs on the firewall and use some contact cleaner but headlight still dodgey.  Have a feelings its the mess behind the intrusment cluster or possibly the fuse holder that merlin mentioned.  I do have a wiring diagram in my haynes workshop manual and will slowly go through it.  Might change relay over.

 I also found out what the extra switch on the dash is.  Someone at sometime has wired up a hazards light as there is an extra flasher there with nothing attached.  Previous owners did a custom dash from cluster to passenger door and i think were a little slap happy hooking everything back up!

Wish me luck!  ;D

good luck.. youll need it. i ended up ripping everything out and put in a good standard wiring loom. i had sparks coming from the indicator stalk:))

funnily enough it seems the indicator stalk might be the culprit.  driving home with one light....turned on highbeams..turned them off and had NO LIGHTS!

Those indicator stalks were a nightmare. I remember I had to run a bridging wire to get my high beam running many years ago when GM wanted to charge me $250 for a new one. Good ones were like hen's teeth even back then. I was wandering through a wreckers about 10 years ago and spotted one while I was looking for something else so jumped on it but it's just sat around since then and I no longer need it seeing as I've swapped steering columns now.

I think it might be a common problem with the indicator stalk, either the contacts wear and cause resistance,  or people change headlights and then it draws to many amps.

Mine has an old style floor mounted dipper switch, but you can still smell that warm insulator smell when the lights are on :D

depends what high/low beam switch ya have? i have the dimmer switch on the floor near the cluch pedal and had the same trouble but in reverse, the high didn't work. turns out it was a dodgy conection on the floor switch. don't know if that helps...

Switches. I had the same problem, so just took apart the stalk indicator and polished the contacts.
Also the best thing to do with lights is run relays for them.
Fit a high conducting wire from the battery to a push blade fuse box mounted in engine bay then run wires to relays for the lights. This bypasses electricity going all the way through the system, through the stalk and just sends power to the lights avoiding over loading the sub-standard Lucas nightmare.

You know why Poms drink warm beer? They only have Lucas refrigerators!

Yep have had many probs in early days of CF with lights. Indicator stalk is the most common prob in CF's, most complain about switching to high and all lights go out. As others have already stated are becoming rare as but remember most BMC lucas stuff is pretty much the same only different plugs on the end, examples are chevette, viva, even the likes of triumph. The good thing is most lucas looms etc all have much the same wiring colour code. If you spend enough time on these looms you will soon learn the colours off the top of your head. I have all the cf one colour code memorised so I can look at a wire colour in a standard CF loom and tell you where it goes to, now how sad is that lol. Maybe I've spent too much time on my bedford and getting to know it lol.

my lights started having problems, but i tracked it down to the connections on the back of the fuses.
the only real way is to rewire the hole bedford with relays for all lights (like moden cars)
realy who use's a fuse for left side low an another for right side low, an its the same for tail an high beams..

i also herd my lighting stick is from a ford, no idea what model. (will be getting changed) to a ford switch (i like the look)

i know my indicator stick is from a ea ford. (installed it myself)

tidyed up all the wiring behind the intrument cluster and the dash pod some one had built and also "fiddled" with the fuse plate and now everything seems to be working.   who the hell would use 3 different colors on a ground wire?  had me swearing my head off for a few hours!

does anyone have a wiring diagram for a 79 bedford that they can scan and email to me please ???
Title: Re: My Bedford Wiring Is A Disgrace!

hey luko, couple of days ago Warren, gave me a copies of beddie wiring diagram, said he got it off the internet, cmon Waz share the secret with us. I think there has also been one downloaded on this site, can't recall where so try a search .... someone will be able to help. My scanner is like my sons that have moved back to live off me .. woops I mean to live at home...... doesn't work  :-\
