After we tested the compression and spark for the second time we concluded from my dad's past knowledge and process of elimination that it could not be the coils or just one switch box that was the problem. Since there was no spark from 1,2,4 and 5 we know that it might be both of the switch boxes that need to be replaced. In order to test the coils we needed to take off the brakes surrounding the pistons which you will see in the first and second picture, we tested the coils to make sure they were all connected and then looked at the switch boxes, our next step would be do undo the screws surrounding the switch boxes take a picture of the wire chart and insert new ones. They cost about one hundred dollars a piece and Mike Nass my dad's friend has a lot of parts so we'll be asking him for a favour. We took off the bracket where the wires all sit as well which you can see in the third picture. If it is not the switch boxes and the problem still continues then the flywheel we need to be taken off with a special piece to get to the stators. In the fourth picture you can see a glass container with metal in it this is a fuse, we wanted to see if there was a crack in it related to our electrical problems. This last picture at the bottom is a picture of what the wiring looks like in the switch boxes so that it can be compared to when they are replaced.

Today my dad and I did a second compression test without putting gas in the night before since it had been six weeks from our last compression test. So in the pictures below it shows the process of what it takes in order to get to the stage of doing the compression test.
This month my parents decided to rebuild our bathroom downstairs and I also got surgery so because of this my capstone unfortunately got pushed back however once I revolver I hope to get right back on it!
In the photo below is a picture of an ohm meter that my dad and I have to purchase because four out of the six cylinders had no spark with the plugs so we have to test the switch boxes and the stator. A switch box is an electrical component of the motor used to channel electricity towards the spark plugs. A stator is an outboard form of an alternator inside a car. If there is low electrical charge when we do the test for the switch boxes than we know that’s the problem and we’ll have to replace them. If the number we get for the test is lower than the guideline like the stator than we know it’s that and it will have to be replace by pulling the flywheel off.
This device that I'm holding in my hand is called a compression tester, how it works is you plug the black hose into the area where the spark plugs would be then you start up the motor and test the compression each cylinder puts out. When my dad and I conducted the test each cylinder had a PSI between 210 and 220 which means the second cylinder likely does not need to be replaced. We also did a spark test to see which plugs were working and found out plug 1,2,4 and 5 were not which means the electrical wiring needs to be looked at.
This is the wiring I needed to connect in order to make the motor run by connecting it to my car, the black and yellow wires are the grounds and the red wire at the bottom of the picture is where I will get my power. The long black tube in the far right of the picture above is the wiring connection, it has prongs on it that connect to the other part that was already within the motor.
Today I looked at the wiring and spark plugs but first I had to take off the parts on the outside of the engine like the cowling and plate. In order to take the cowling off you need to unclip three clips you can see to the right in the picture. Then you can take off the top part of the motor that's covering the flywheel by unclipping the top part.
This is the motor the day we got it into the garage, as you can see in the photo it came on a stand so it's much easier to move around. The object surrounded in red is the extra gaskets provided. The box surrounded in blue is the extra pistons and connecting rods I might need to replace within the motor. The wires surrounded in green is the throttle cable which will be used during the compression test to give power to the motor.
