Sealine 190 Ignition Issue

Hi All

Apologies if i have posted this in the wrong section.

I have a Sealine 190 (1988-1990), basics are, it wouldn't start, so we replaced the Alternator, cap, rotor arm still no spark, turned over ok, but no spark.

Got it down to the ignition coil and then to the 8 terminal module, it's this that we need to replace, but i have had more luck finding Lord Lucan, one appeared in the US but that has gone, so my question to you all, we want to bypass the module and stick an electronic ignition conversion kit, but how the hell do i know what one to buy, the engine is an AQ171C 2.3L Petrol

Note: Or any kit to start it up, it has been sat in a marina for 16 months and not moved, i need this baby to start, please, any ideas?? i'm in the UK and near Reading, Berkshire.

If anyone has any info, i would be eternally grateful for some, this has been an arduous last 16 months.

Thank you.
 
Nope, correct forum...
FIRST... stop throwing expensive parts @ this problem. An alternator has nothing to do with an engine's inability to start ( as opposed to crank). ALL it does is recharge the battery. An engine will happily start and run ( for awhile!) on just a battery... no alternator.
SECOND... before offering assistance, it helps to understand your comfort level with tools and test equipment. So...???
THIRD.... assuming some moderate level of comfort with such things ( or the willingness to learn...)
a) Do you have a means to measure voltage, i.e., a voltmeter or a multimeter (the least expensive analog one will do)... or at least a test light?
b) Did you download the (free) USER MANUAL from the Volvopenta website* for your engine?
there is a wiring diagram in that manual that has sufficient detail for you to isolate your problem.
FOURTH... There are a number of tests I'd do if this were my boat before I went crazy shopping for a new ignition system.

http://www.volvopenta.com/VOLVOPENTA/NA/EN-US/MARINE_LEISURE_ENGINES/OUT_OF_PRODUCTION_ENGINES/Pages/out_of_production_engines.aspx

Enter this exact text string in the "Product Description" box: AQ171C (AQ)
Click on "SEARCH"

Click on the entry "OPERATOR'S MANUAL" (the one that is underlined!) in the table that will eventually pop up and then click on "AGREE" in the copyright popup.
Down load the manual (7746277_en.pdf). Lots of good info for you in this, however, for your presenting issue, go to page #25 for the wiring diagram for your engine. You will be using this diagram, together with your voltage testing tool to determine which of several things are wrong with your system. For example: are you getting +12 from the key to the module -or- Bad connections? -or- defective pickup in the disti?

Hi.

Thanks for the tips, the alternator needed changing, i just added that to the strength of my woes, i have measured, tested everything and followed it down to the module, had the module tested and it is faulty.
 
Well... Lacking a source for an OEM part, your next best bet might be a PERTRONIX kit. Contact them and ask (www.per....com). One big issue is .... does your existing distributor have a mechanical advance?... IFSO your chances are fairly good.
