Lucas YXB135 ignition (igniter) module tester

Hi All- followers of this blog may recall that I recently had the joyous experience of tracing an intermittent ignition fault. Although this was ultimately due to a duff ignition switch I got confused, as I had swapped the DAB125 module inside the AB14 as a first step in order to eliminate this as a fault. Sad to say the new Intermotor module I had used was actually faulty itself and this stopped me from solving the problem by changing the switch. When I eventually refitted the old module all was well.

I wanted to avoid a recurrence and although I did get a testing protocol for these modules eventually, I also found that Lucas had produced a dedicated module tester the YWB135 which can test a whole variety of modules.

This seemed really useful so when one of these came up on Ebay I grabbed it. However caveat emptor clearly applied, and although the unit did come with an instruction booklet, the description failed to mention that in fact there should be 2! I am lacking the red covered book which contains the operating instructions, test procedures and how to interpret the results.

Well I did eventually get the instructions and I'm greatly indebted to Bos Automaterialen of the Netherlands for copying a booklet he had in stock- at no charge! You dont get service like that very often these days! Anyway Many thanks Bos! If anyone would like to visit/like his facebook page you will find it here.

Just in case anyone is curious (and for backup purposes) I'm posting the pics here:

Great to say the module I have fitted passed the test, the "new" Intermotor part I had bought previously failed. I ordered another from China at only £12 I wasn't too confident and I've not tested it in the car yet, but I did put it through the meter test and it passed fine! I will keep this one as a spare.
