partially full of water , this was shorting out the lamp curcuit when braking , deeper investigation found that the lip under the rubber weather trim had rusted away in several places allowing water to enter the interior ,AND ,after opening the unit I found the curcuit board had corroded away --see picture above . I will now repair the lip and search for another unit , this one has been eaten away too! . The next unit I get , I will drill some drainage holes in the cover and then reassemble , purely as a secondary precaution.

Well remove and replace the faulty parts. Should be easy enough, go to Radio Shack for the parts. The board is fine, just repair it.

Hi Ranma ,Thanks for your feedback , I did try that but unfortunately they did not have the EXACT replacements .The capacitors are : 25v 471J = 470pf ( x4 ) , J= +/- 5% , 473Z = 0.047 ( x 2 ) ( no suffix- presume farad? ) Z = + 80% /- 20% ,checked all this on Google , also , the single row integrated curcuit blocks part number MB4210 8804 M83 ( 8 legs ) do not show up anywhere . Can anyone shed some light on the capacitor voltage as the only replacements are 16v , 100v and higher .Thanks.I am not up to speed with electronic components so I would rather replace with like for like or replace with another unit .

I have found a curcuit board repairer and I have had my board ( lamp fail unit part number 89373-14020 ) repaired by :

R and G Technology
Unit 10 Silverdale Industrial Estate
Worthing
West Sussex
BN11 2RZ

Tel 01903 202345 mailto:sales@randgtechnology.co.uk

I am very pleased with the results and I now have the unit refitted and working again . Below are the pictures of the board in after and before state .








I recommend this Company if you have any curcuit board problems .
