Maverik Posted May 17, 2013 Share Posted May 17, 2013 Hi guys, looking for some more idea please for places to look for my problem. Vehicle is 1991 Stock(ish) 200tdi CSW Problem is the wiper does one wipe, whenever you turn the headlamps on, or flash the high beam. Other symptoms: I had the left hand front indicator and side light removed from the harness, with the side light removed and the indicator installed the indicator made the wiper go, but then with the side light installed that stopped and then the headlight made the wiper move... Things done already. Local earth's installed on wiper relay. Earth checks done to wiper motor, engine bay earth point. Wiper relay swapped out for alternative Indicator stalk changed out for an alternative Wiper stalk changed out for alternative Anyone got any more idea's of things for me to check or pearls of wisdom?

western Posted May 17, 2013 Share Posted May 17, 2013 thought you found the problem area on the loom Quote Link to comment Share on other sites More sharing options...
Maverik Posted May 17, 2013 Author Share Posted May 17, 2013 I thought I had too... but alas no. I've got ST3333 in front of me and some other wiring helps, going to have a go at it in a bit see if I can find the leak... Quote Link to comment Share on other sites More sharing options...
western Posted May 17, 2013 Share Posted May 17, 2013 wiring from the 2 stalks from the main loom connector to the damaged area you found, still sounds like a burnt or chaffed wire shorting between circuits. Quote Link to comment Share on other sites More sharing options...
rekab69 Posted May 17, 2013 Share Posted May 17, 2013 Hi, I had all sorts of strange problems with lights / wipers / washers turned out the loom had fused together inside the passenger wing. Might be worth a look.. good luck.. Cheers, db. Quote Link to comment Share on other sites More sharing options...
eds Posted May 17, 2013 Share Posted May 17, 2013 I also haVE THIS PROBLEM AND BEFORE I COULD FIND A SOLUTION I put an isolator switch in the circuit so I could turn them off when not needed as you will soon knacker the morot dry wiping. I eventually found my fault which was a bare wire behind the fuse box, I think! I did do all my earths all round the vehicle too which is a good job anyway. I still use the isolator switch just out of habit. Quote Link to comment Share on other sites More sharing options...
Maverik Posted May 20, 2013 Author Share Posted May 20, 2013 After doing some fault finding on Friday, I've worked out I've got a stray 1.2 Volts (when the headlights are switched on) leaking into the Light Green/Black wire that feeds the wiper relay. I traced it back to the front windscreen washer bottle pump motor, when this was disconected the fault went away - so my thinking is its leaking back up the washer pump earth, but need to double check that, LG/B is actually hooked up to quite a few different circuits, so just been trying to isolate the voltage "leak". Its either a shorting wire or a bad earth, got some new bullet connectors comming from Autosparks, plan on re-locating that passanger side earth and generally try and tudy up the connectors down there see if that helps.

Maverik Posted May 21, 2013 Author Share Posted May 21, 2013 To confirm, there was definetly 1.2V going back up the earth on the squisher pump circuit, re-made the earth block to the wing with some new bullet connectors and cleaned the wing earth and problem still persisted, I found by unplugging the headlight earth and running this back to the battery solved the issue, but cleaning up the local earth did not, which is now making me think the wing itself has managed to isolate itself from the chassis, to get things working again I've put a diode inline with the negative on the squisher motor, which means its stopping the leak going back up into the wiper circuit, but its slowed the pump down when the headlights are on, once the dash is re-installed I shall have a look at the wing bolts themselves, they looked pretty minging and corroded so won't tackle them till I've got the interior of the truck put back. I temprary solution, but at least I've identified the problem. Quote Link to comment Share on other sites More sharing options...
Aragorn Posted May 21, 2013 Share Posted May 21, 2013 Perhaps just add a short earth strap between the wing and chassis/bulkhead? Quote Link to comment Share on other sites More sharing options...
highlandmist Posted October 29, 2014 Share Posted October 29, 2014 Jumped into this thread as it precedes mine and it's the same problem. I may get a look at it this weekend, weather permitting. I have fixed every problem so far but electrics is a weak point of mine Replaced the stalk and the main light switch but not the washer stalk. I tried disconnecting it when I did the main stalk but couldn't ? Do you remember having problems getting it off ? Also, what diodes do I need to buy ?
