If I understand correctly, I need to do the following:
1) Get rid of the yellow wire completely along with the ballast resistor
2) Get rid of the orange>red wire that goes to the starter solenoid.
3) Run the purple wire directly to the + side of my new coil.
This will leave me with 2 purple...
I was able to find my engine Serial Number (F810329)
Can anyone tell me the correct way to route the Purple wire? In the "Spliced wires" picture, the purple wire is spliced with the orange>red wire going to the starter solenoid. I will eliminate the yellow wire and ballast resistor that was...
Thanks for all your replies and help. I'm going to order the proper coil.
I will be tied up for a couple days but will try to get the engine serial number and post it.
Again, thank you very much for your help!
I have a aftermarket electrical fuel pump. The blue wire goes from the + coil solenoid to what looks like a oil pressure switch on the side of the block.
There is a block plate in place of the mechanical fuel pump.
Wow, this makes me pause. I really want to get it back to original.
I will have to get that serial number. Hopefully tomorrow afternoon.
Thanks for your help
Ohh man your awesome. I agree with your assessment of the previous owner. You should have seen the nightmare starter situation I had to fix last year.
I want to fix the wiring. In pic #3 labeled "Spliced Wires", the "red" wire with a butt connector has a splice with 2 leads. Red to the starter...
I was boating and my 1996 Crownline 7.4 Mercruiser stalled. I tried starting and noticed spark at the top of the coil. I was coming out the side of the tower. It looks like the previous owner put an automotive coil on.
So, not being a electical mechanic, I began trying to figure out what...
I have a 96 Mercruiser 7.4 on a Crownline 225br. I'm not sure what ignition I have. The serial number is F810329.
Mercruiser shows the spark plug gap could be .35 or .40 depending on the ignition type.
Can anyone tell me what my ignition type is and what the gap should be?
Just to be sure, I installed the 2 wire switch from a T at the oil pressure switch.
On one side of the 2 wires switch - I run to the Purple ignition wire?
On the other side of the 2 wire switch - I run wire to the small stud on starter solenoid then to the fuel pump?
Or should I make a T and...
I like simple. Thanks!
Where would I mount the switch?
Would you recommend any particular switch?
Also, should I remount the purple wire in pic 1?
Really appreciate all the help!
