Easiest way to change 3.5 V8 ignition module

Recommended Posts

I need to change the ignition amp strapped to the side of the dizzy (given that some inconsiderate previous owner was not kind enought to relocate it to the inner wing!), so whats the quickest/best way - leave dizzy in situ and strip out alternator and pas pump, (actually would the dizzy rotate enough to expose the module screws if the dizzy clamp was loosened?). Or remove dizzy completely (after of course ensuring TDC, checking rotor position, and cursin trying to get correct meshing back again).

I haven't really looked yet, just trying to get heads up on best practice before I start. Thanks in advance, Joe

Yes, remove the distributor. That will make it easier to figure out how you're going to extend the wiring, too. If you look here: http://www.aulro.com/afvb/technical-chatter/96950-lucas-ignition-amplifier-replacement-bosch-024-a.html and don't mind a bit of reading, there's great stuff about replacing the Lucas amp, which is junk anyway.

Cheers Davo. Great thought in that aulro post - only problem here is sourcing the bosch module, I had a quick look in a bosch catalogue: http://www.pim-engineering.com/tiedostot/Bosch ignition_modules.pdf. and the only way to find a BIM024 in uk was on some mitsi, toy and nissan vehicles. Sounds like a good module though 'cos it also fires Bronco v8s and the Holdens. I'll keep my eyes open in the scrapyards...

You Don t need to get to tdc.  Simply put a blob of paint where the dizzy body meets the front cover and put another blob where the rotor arm is pointing. ...

Cheers mate, youre right, I'm going to check out the whole timing thing while I'm at it 'cos I've never seen this engine run, so its back to all the basic checks. Once the module is off I also need to check the inductive pickup on the dizzy, just to (hopefully) rule that out

This may help: http://www.v8forum.co.uk/forum/viewtopic.php?t=78&postdays=0&postorder=asc&start=0 They're talking about a module found in all sorts of cars. As long as you work out which pin attaches to what, you'll be right. You need the correct coil as well. It's quite a bit of reading and mucking about, (I know because I did it all a few years ago), but worth it to replace the Lucas stuff.
