ratfinkd1,
Well, my standard advice is to power up the PAMCO and coil with an external battery that is not connected to the bikes charging system until you have verified that the PMA is working properly and not producing a high voltage, like 20+ volts, or no voltage at all.
Don't leave the power to the PAMCO and coil on if the engine doesn't start as that will fry the coil and the PAMCO.
I also recommend that you wear safety glasses until you have got the PMA working properly because if it does produce 20+ volts on initial startup and you don't catch it right away and shut it off, the battery will boil and possibly spew acid all over everything.
You need to check your states regulations for minimum equipment required, like a horn and turn signals. You may also need these items to pass vehicle inspection.
If you do not have these safety items on your bike and you have an accident that is your fault, then your insurance company will be upset and may come back to you for the settlement, especially if you injured someone, like yourself or your girl friend riding on the back.
If the accident is not your fault, then the other party's insurance company will come after you for contributory negligence. You can argue with the judge that the horn and turn signals had nothing to do with the accident, but that won't get you very far.
If the missing horn or turn signals contributed directly to the accident, then you are dead meat, perhaps literaly.....
It gets worse....even if your state says you don't need turn signals or a horn and it's OK to ride buck naked without a helmet, when you applied for your insurance, there was this little question, like "Has the motorcycle been altered, modified or otherwise screwed with?" and you answered "no" because you knew if you answered "yes" they would probably not insure you. Well, that's called insurance fraud...
.....now, you are really in deep doo doo...
So, I guess what I am trying to say here in answer to your original question is..
...keep the horn and turn signals.....
Good luck....
