I have edited the picture to show what to do.

  1. The power wire from the generator is wired to the points wire.
  2. The points wire and generator wire are wire to the coil +
  3. The coil is frame grounded when mounted.

Note:You may need to try each of the 2 wires from the generator(try one and if it doesn't run or run right,try the other wire,Since the energize at different times)

No spark from coil to distrubuter

Disconnect the ignition coil output wire at the distributor cap.
Connect a spark plug to the end of the ignition coil output wire which you just disconnected.
Connect a ground wire to the threaded portion of the spark plug.
Disconnect the ignition coil ground wire from the negative terminal on the coil (Green Wire).
Connect one end of a ground wire to the ignition coil negative terminal.
Turn the ignition switch to the ON position.
Tap the other end of the ignition coil ground wire jumper on an good grounding point (for example the battery negative terminal) and look for sparks at the spark plug that correspond to the frequency of your tapping of the ground wire.
If you have a good spark at the spark plug, the ignition coil is good.
If you don't get a good spark, check for approximately 12 VDC from the coil positive terminal (black wire) to ground with the ignition switch in the ON position. You should also get approximately 12 VDC from the coil negative terminal (Green wire) to ground
Ignition Coil Resistance Check

In addition to the test above, you may elect to perform an ignition coil resistance check as confirmation of the coil's condition.

Check the ignition coil primary coil resistance by connecting an ohmmeter between the positive (Black wire) and negative (Green wire) terminals on the coil. The resistance should be 0.4 to 0.6 ohms.
Check the ignition coil secondary coil resistance by connecting an ohmmeter between the coil output terminal and the ignition coil negative terminal. The resistance should be 5000 to 7200 ohms.

You may have a bad coil or bad ground or wire connection

Tem my briggs portable generator has no spark it appears ignition coil has failed. Items checked. disconnected kill wire to coil, disconnected oil sensor wire no spark this will be the 2nd coil

Test the coil electrically
A digital multimeter is required for testing the resistance levels of the ignition coil. The terminals of the coil are going to be marked "negative" and "positive," and these are the two points where the resistance of primary winding can be measured. Step 1: Prepare the multimeter
To check a 12 volt coil, set the multimeter to at least a 200 Ohms setting. Attach both leads of the meter to the coil-terminals with black to the negative terminal and red to the positive one.
Step 2: Test the resistance
The normal, acceptable range for a standard 12-volt car is 1.5 to 1.7 Ohms. See if the reading is within this range.
Step 3: Test the secondary coil resistance
Set the meter to 20K Ohm setting, and attach the leads to the ignition coil's center terminal. The reading for secondary-coil resistance should be 11, because if it is lower

Where does the wire that comes from the negative side of the coil go too?

There is usually a wire from the coil that goes to the negative side of the coil while the positive side goes to the ignition switch. Without knowing more about your car and engine, that is the best info I can provide.

Wiring rectifier correctly?

You are discussing a bridge rectifier, the + connector is directly opposite the negative connector, the remaining two connection points are the AC side of the rectifier + AC

How to tell the negative wire on a ignition coil on a 93 dodge w150

Usually the negative wire will be black on most vehicles. Also, the negative terminal will only have a single wire, the positive can have two coming into it.

How to hook up a dual voice coil subwoofer

The problem with dual voice coil subs is that the amplifier must be able to drive the load. I am assuming that each coil is 2Ohms each and the amplifier you are driving the subwoofer with is capable of driving that load. If this assumption (of the VC) is true your Amplifier will need to power the 2Ohms of the VC this will be "Normal". If the Amplifier is not capable of powering less than 4Ohms you will need to wire the subwoofer in "Series". If the Amplifier is capable of powering half the VC's resistance you can wire it in "Parallel". Normal wiring is going to be, Positive on the Amplifier goes to the Positive (red) side on the subwoofer and Negative on the Amplifier goes to the Negative (black) side on the subwoofer, then repeat this for the other output side of the Amplifier to the other VC, easy: This is "Series". Now if the amplifier is not capable of driving the load this gets slightly complicated. Positive from one of the positives on the amplifier goes to one positive side of the speaker. Negative goes to the opposite coils Negative side (black), now you get a short wire of your preference from the Negative that has no other input and run it to the opposite Positive side that has no other input: This is called "Parallel". If the Amplifier is capable of running a load lower than the resistance rating of the subwoofer then run the wire from Positive on the Amplifier to Positive on the subwoofer and Negative on the Amplifier to Negative on the subwoofer, and then run a short wire of your preference from the first VC to the other VC, Positive to Positive and Negative to Negative. Double check the wiring Red to Red and Black to Black in everything but "Series". Take it easy and don't wake the dead, I did that in the middle of the day they don't like being waken from their slumber.

It will not rev up

Not farmiliar with the model But you are reading positive on the neg. side of the coil because it is not grounding off & on through the points or Black box ignition system. That's what makes the coil spark. If you touch a grounded wire to the NEGATIVE side of the coil, You should see spark each time you break the gound connection. Now you need to see why your CDI system is not working. Most of the time, It is a bad pulser coil on the input to the Black Box, Possibly the Black Box but rare for most models ( check on your model with a serv. tech. ) It is not the ignition coil. It has good continuity & B+ power to it. Also a serv. tech for that model could tell you if it has any other Safety Systems that would kill thr spark for a reason.

All I can say about it is Motor out of the frame. One just have to do a compression test before pulling the motor. Not real good. If not satisfied pour a bit of oil in the sparkplug hole and tested again, almost 130 lbs. Top end time. When the oil will be drained the oil from the frame, the first thing out was several ounces of water.
