Greetings everyone. First jeep ever!

I’ve got three projects to start with: wiring the back license plate for the light, installing and wiring the wiper motors, tracking down a leakage from the transfer case (hopefully only the fill plug and seal).
Who is a good reputable source for electrical diagnostic equipment in case I need to replace what I have. Timing light, ammeter, etc.

A couple of questions in regard to how your M38A1 is configured? Is the electrical system still 24 volt? Are you running the waterproof plugs and wires? The waterproof wires require an adapter to go in between the plug and wires for a timing light. You can pull the waterproof plug wire and spark plug and replace it with a conventional plug and wire so you can use an induction pick up clamp of a traditional timing light. A conventional timing light can be used, but ensure that you only hook the power lead to the 12 volt lead of the battery set. This will work with the ignition timing, but if you wish to check your dwell, then you'll need the engine ignition timing set.

There are a few good sources for Automotive testing equipment. In the end it is the brand name and place of manufacture you are looking for. You can shop prices at a lot of places. I am very fond of Fluke when it comes to Multi-Meters. I always try to buy USA or Japanese testing equipment. You will need a Multi-Meter. It does not have to be a Fluke or an expensive meter. Your electrical work will be basic. You will not need precision accuracy. An inexpensive Multi-Meter will definitely do the job. For the timing, it is best done by setting the Timing when the points open and referencing the Flywheel markings, no timing light is required. If you want to use a light, follow gm's suggestions. You can use your Multi-Meter to detect the instant the points open. The dwell is directly affected by the point gap. This is best set with a good feeler gauge. A dwell meter can be used to see if the points are operating correctly, but it is not absolutely needed.

It runs a 12 volt system. At some point I’d like to do the waterproof system if practical. Thank you for the input fellas.

12 volts make life a lot less troublesome. Most of the reason for folks to convert from 24 to 12 is mainly the costs involved with replacement parts.
