Popular Post Lionhound Posted August 18, 2016 Popular Post Share Posted August 18, 2016 Like it says in the title really. Got an ex MoD 90 wiring has been "repaired" in the past ?. Whoever the muppet who fancied himself as an auto electrician was, he must have owned shares in red insulating tape. I have indicators, brake lights, front and rear sidelights, headlights on dip, 1 headlight on full (could just be bulb, sealed units). I have lethargic wipers which have normal speed and high speed. The high is in the right place, all other positions are slow. Occassionally they park but 90% of time stopping them is a pull the fuse job. Hazard lights? Eh, no. I also have a full loom of another 90. From look of the spaghetti under the bonnet and behind switches, I think this might be the best option. Is it possible to alter it to suit the military version or do I just go normal 90. Who needs convoy lights anyway. Help or insight appreciated ladies and gentlemen.

Maverik Posted August 19, 2016 Share Posted August 19, 2016 Just thinking 12v - 24v? if its converted to 12v from 24v the wipers might be slow if the motor hasn't been changed to a 12v one...? Quote Link to comment Share on other sites More sharing options...
Eightpot Posted August 19, 2016 Share Posted August 19, 2016 MoD 90's/110s are all 12v with rare exceptions. If it has the old style glass fuses, the clips that hold them in place get dirty and corroded - give the offending fuse a wiggle and you may find wipers speed up or headlamp comes on. Check the headlamp connector plug with a voltmeter to see if it's getting power first, then you'll know if it's bulb or fuse or connector The lucas bullet connectors also get dirty and corroded, so undo and clean up any that are on an offending circuit. Also check and clean earth points - there's one under the wiper motor. Hazard lights - probably just need a new hazard light switch but theres a good fault finding thread on the forum to help narrow down the problem. Military loom is the same as the civilian one, military ones just have a couple of extra add ons for convoy lights and rotary switch but you can still connect these in.

Tal Posted August 19, 2016 Share Posted August 19, 2016 can I have the red tape when you're done? My only advice here is take it one thing at a time and trace it all right back to the relays and battery, replace anything and everything that looks messed up and make sure its earthed and works properly before you get distracted by the next bit. other than that....I wish you good luck and lots of coffee oh and some unique coloured tape for anything you already traced.

Lionhound Posted August 20, 2016 Author Share Posted August 20, 2016 Thank you aĺl for your help. It is 12v but will check it all out. Methodical is good advice. Have to admit to spitting the dummy and trying another bit instead but will heed your advice. Quote Link to comment Share on other sites More sharing options...
