Title: electronic ignition Post by: smithy on January 27, 2003, 10:04:05 PM hi all, just got my hands on an electronic ignition distributor out of a early commodore and was wondering what mods if any are needed to match it up with the good old 186? does the dizzy ned to be re-curved etc, or will it just slot in.
any suggestions would be great dean Title: Re: electronic ignition Post by: slim on January 27, 2003, 11:12:16 PM It will slot straight in, but best to change the coil at the same time, :o.

just wanted to make sure. dean Title: Re: electronic ignition Post by: slim on January 28, 2003, 09:37:52 AM It is something I do to all my red motors. There heaps better, and almost maintenance free.

As Slim said they are a good dizy work real well but make sure you use the 13 volt coil with it. Its also a good idea to test that you are getting 12 to 13 volts into the coil, I had trouble with one in my car it was breaking down at high RPM, I then tested the elec system and found the coil was only getting a max of 10 volts (Voltage drop in the wirering) so I took the easy way out and installed a small 40 amp regulator to the coil and bingo runs like a dream. Also you may have to open up the gaps on your spark plugs, I have set mine at 1.0mm and find its running quite good. I'm running a red HP block set up to 186's specks Hope this helps, Steve Title: Re: electronic ignition Post by: smithy on January 30, 2003, 10:21:07 AM cheers for that digger i'll keep it in mind.
one thing i will say though, half a day,several grades of wet and dry and a couple o sqirts of autosol and they do polish up a treat ;D dean Title: Re: electronic ignition Post by: Digger on January 30, 2003, 01:12:42 PM Yes they do come up pretty good, but I find they tarnish off real quick.

I've been reading the forum with interest as I'm doing some tinkering with my 186 (HR) Re. the electronic ignition changeover, what happens to the vacuum advance? If it's ignored then what is the effect on the engine perrormance? I appreciate all comment Title: Re: electronic ignition Post by: ACE on March 20, 2004, 02:00:34 AM Hi Knightmare,
If you are modifying your car for drag racing only disconnect the vacuum advance and modify the mechanical advance to suit.If it's for street use i'd keep the vacuum advance connected. The vacuum advance unit is there for a reason. Car manufacturers wouldn't fit them if they didn't have to. It provides advance in relation to load. By disconnecting the vacuum advance you'd probably get a bit less performance and fuel economy. Hope this helps, Regards ACE 8) Title: Re: electronic ignition Post by: EJ_Dave on August 07, 2006, 09:11:42 PM Hi all,
just trying to do fit an electronic (blue motor) distrib myself. It has 3 wires whereas the old one had only 1 (low tension). Where do the other 2 hook up?? Cheers, Dave Title: Re: electronic ignition Post by: Dr_Terry on August 08, 2006, 01:12:40 AM Hi Dave.
AFAIK all Blue motor distributors (AKA Bosch HEI) have only 2 wires, a Pink one & a Green one. Somebody may have modified the wiring for an alarm or similar, check to see what's actually coming out of the distributor's case. Make sure it's a Bosch HEI dissy, by the way, there are other types, if unsure post the numbers off the case of the dissy. Dr Terry.

At least I managed to get my motor going with a points distributor. Unfortunately there was no spark to no4 cylinder. After scratching my head for a while I discovered the distributor shaft was bent and the rotor was actually pushing the cap around in a kind of belly dance action when running. I guess the points gap varied a bit too. Hopefully the swap to an electronic distributor will go smoothly. As it's my daily driver car, I'm starting to miss it a bit after a week off the road. My wife is starting to ask if a red motor will really be that much better than the grey that has served me perfectly well for the last 6 years. I'm beginning to wonder myself. Cheers, Dave Title: Re: electronic ignition Post by: EJ_Dave on August 08, 2006, 09:11:11 PM Hi Dr Terry,
It looks like I have the right dizzy. There are really only the pink and green wires but another wire has been joined to the green one for some reason. So where do these 2 wires attach? Thanks, Dave Title: Re: electronic ignition Post by: Glenn 'Stinky' Stankevicius on August 08, 2006, 10:04:45 PM It might be for the Tacho ???
Title: Re: electronic ignition Post by: Dr_Terry on August 08, 2006, 10:04:53 PM Hi Dave.
The pink wire goes to the +ve of the ignition coil & the green goes to the -ve. The +ve ignition supply wire also goes to the +ve terminal of the coil. You must use the correct HEI type coil & the +ve must be a full 12 volts (no resistor in the circuit), all Grey motor cars were originally wired that way anyway. The extra wire that has been added to the green dissy wire was probably for a tacho. Dr Terry. |
