86 Oldsmobile coil problem |
|
|
Our 86 Oldsmobile Delta 88 has a problem with its distrubutorless coil. We
bought it new back in 1986.
There are 6 cylinders.
There are 3 coils.
Problem: The middle coil that fires cylinders 2 and 5 has no spark.
We have never worked on distributorless coils. We are just your average
weekend mechanics.
Question: Do we have to buy an entire new coil back with the 3 coils, or can
we just buy a single middle coil that sends a spark to cylinders 2 and 5?
Can we take the coil pack apart and clean some of the contacts?
Any help would be appreciated.

You need to buy the whole coil as its all one unit. Chevy Dealer list
price in July was $127.00 for my coil, my cost through a buddy's
discount was $89.00
4 -6 screws hold it down, remove the ignition wires and the wires
underneath the coil that connect to the ignition module.
You might want to get the gasket that goes between the coil & ign
Module. It will no doubt break apart when you remove the coil.
Good Luck !

If you want to stick with a GM Coil any GM dealer would be able to
order one for you if one is not in stock.

You can most likely get one at any salvage yard. |

Are you certain it is the coil. You should be able to verify that with a
resistance check once you get the coils unplugged. I would be more
suspicious of the module.

Perhaps this article can be of some help to you:
http://www.motorage.com/motorage/article/articleDetail.jsp?id=20037
My 92 G/A has 3 separate coils. Each measures about .5 ohms on the
primary side and about 11 ohms on the secondary.
However, measuring the ohms won't tell you if the
insulation breaks down when hot and under a 30kv load.
A bad plug or wire will destroy a coil. It will then cascade the
current and destroy part of the ign.mod. |

Thanks for your help.
Resistance check: Could you please go into more details how I can do a
resistance check on the coils?
What should the resistance readings be? Thanks.
I have never worked on this distributorless coil in our 86 Oldsmobile even
though we bought the car new in '86.
We know very little on how this type of coil works or how to work on it.
We have been trying to educate ourselves on this distributorless system by
studying our 86 Olds Haynes book and by checking out auto sites on the web.
Still, trying to replace or check out the coil and module assembly is new to
us.
We keep the car around for sentimental reasons. Our main car is a 1998 Dodge
large passenger van that seats 7 and that has about 100,000 miles on it.
We have been lucky with the 86 Oldsmobile, because the coil is the
original coil that came with the car.
Module: How can we check that the source of the no-spark problem to
cylinders 2 and 5 is the module instead of the coil that provides juice to
cylinders 2 and 5?
The reason I ask is that the module seems like it is hard to take off,
because the 3 nuts that hold the module to the engine are in hard to reach
places.
Thanks for any help.

The only resistance measurement you can make without pulling the coils is
the secondary. There should be a reading from plug wires 2 to 5. It
should be the same as you would read from 1 to 4 and 3 to 6.
I am not real certain just how that module is fastened but I think there are
screws that hold the coil and module together. Then you will see wires from
the module to the coils. I think they are just spade lugs that slide on.
They could be dirty too I suppose. There is one wire that attaches to all
three coils. I expect that is 12 volts. There are separate wires to each
coil that come from the module.
I will send an email with a diagram that may be similar to your
installation.. |

Does anyone have an idea on how much an ignition module costs for the 86
Oldsmobile Delta 88 distributorless coil system?
Do we have to buy the coils and the ignition module as one set, or can we
buy the coils and the module separately? Thanks.

Thanks for the link. I'm sure the information at the above link will help me
a lot in trying to understand the 86 Oldsmobile distributorless coil system. |

The coil & Ignition module are available seperately. I think the module
is in the $150 to $175 range, but don't quote me on it.
Good Luck.
