Anyone know what the output should be on the trickle charge side of a regulator,just tested mine and it is showing 4+ volts.

if it's a 6v regulator I would expect 7v+ and a 12v would be 14+

Was this under load, or open circuit. You'll find that most regulators need a load across them to pull the power through.

the trickle charge output will be much lower as it's only half-wave rectified. Then depending on your meter it may make it look lower.
You really need a true RMS meter to get a meaningful reading on noisy supplies like that.
Plus, low rpm (tickover) will cause a further reduction.

Try fitting one of these.

It shows a green LED when the battery is charging and a red LED when it is not charging. Simple. It is also a useful indicator that the ignition is switched on.

Is that a BGM AC/DC regulator?

More like half of that. But like I say, you need a true rms meter as it's unlikely to be a pure sine wave.
