Constant heavy charging
It sounds like the sniper, hyperkspark and 'lectric pump are tapped into the battery side of the ammeter.
Normally this side only has the battery on it. So the ammeter shows either battery charge or discharge.
But if you've added other items on it, then the ammeter shows the current flowing from the alternator to those items as well as battery charging.
Basic power circuit on most years is something like this:
If you really like having an ammeter, you could probably wire a fuse/breaker box for the new equipment off of the alternator.
Then use a heavy duty relay to connect the battery to the sniper-pump fuse box when the key is in start.
This way the fusible link, ammeter and all the connections in-between would not be subject to the additional power draw of the new equipment during start or run.
