Thread: 186 Engine problem NEED HELP

the unit I ahve installed is: Holden 186 202 Electronic Distributor HEI Biult IN Coil Includes NEW Leads Black | eBay

So it has an built in coil and came with new leads.

2. Are you using the original coil +ve wire or have you run a new decent sized wire from the ignition switch (correct)?
Original wiring. What sort of current will this sucker be pulling????

3. Have you double/triple checked the timing order? 1-5-3-6-2-4 clockwise.

Double triple quadruple quintuple even!!

4. Have you checked the dissy rotor is in the correct position with regards to the contacts in the cap? These dissies fire when the pointy star rotor lines up its teeth with the teeth on the pickup around it. The rotor must overlap the cap contact under no vacuum and full vacuum conditions. Mark the position of no.1 lead position accurately on the dissy base so you can see it with the cap off. I've seen rough handling shear the locating lug out of the rotor.

Double checked, triple checked.

5. Have you closely inspected ALL the lead contact clips for burning and damage?

As per previous - all brand spanking new.

6. Have you got a timing light to check the timing? Under $40 on ebay you know.

NO timing light.... wouldn't know what to do with it anyway...

7. Have you got the correct cap and rotor, genuine and spotlessly clean, not chinese copy rubbish?

It's a complete change out unit.... all of it is new

8. Are the screws holding the ignition module to the dissy base clean and tight?

Yes...

9. Is there heat sink paste under the module?

Umm???? Please explain....

10.Are the wires to the module loose?

Nope checked that


That should keep you going for a few minutes...

Thanks for the reply

Make sure that you have the sump and pick up off either a HK T or G these sumps have the lowest part in the middle. This will prevent oil starvation when decending steep grades.

D Mac, I will check that....

bee utey,

Just checked the voltage at on the active to the dizzy, shows me 12.7. Batt is at 12.8. Is it worth putting in a slightly bigger wire? 15A do the trick?

Aah, I originally thought you bought a real Holden one like this:

Electronic Ignition EH HD HR HK HT HG HQ HJ HX LC LJ LH LX UC Holden Torana | eBay

The one you have is a total unknown to me, probably made by the bucket load in China and marked up 1000% for ozzie retail. I wouldn't touch one with a 40 foot pole, myself.

Anyway, the point of the power wire for the dissy is that the points system contains a resistor that comes into play as soon as a load appears on it. Measuring the voltage with the engine stopped is irrelevant. Put a 55W globe on it as a load THEN measure the voltage. Run a new wire and see if it helps, then consider buying a brand name dissy (Bosch, Holden) instead of a boy racer special.

I couldn't afford a holden one so boy racer it was

I will give the wire a poke and see.... can't make it worse can it!

Also getting me a new PCV kit! hopefully that will sort out some of the flat spot that was there before my tuning issues....

A new accellerator pump will probably cure that Nick.

hmmm..... probably...

the plan is to bin that carbi anyway.... going to get another one or better quality on there. the current one leaks fuel everywhere all the time. and yes it's had a carbi kit through it only a couple 1000kms ago. (about 200kms before you drove in it)
