Sounds like your bike has DC-powered "4-pin" CDI with electric start,
but
you got a "5-pin" CDI which is powered by AC from the magneto.
The battery tried to power up the 5-pin CDI and toasted it, which I have seen done several times.
Does your ORIGINAL CDI box have a single plug, or two?
On the bike what are the wire colors? How many wires?
I have illustrations that may help after you identify the wiring.

OK just trying to be clear, because I am totally confused by:
"6 pins only uses 4 of them with 4 wires on the 2nd plug onlyone red wire is used on te other plug 1 blue 2 black"
Some of these wires have stripes, such as Blue/White. Look carefully at the wires, roll the wires around in your fingers inspecting for stripes.
So help me, help you... please fill the blanks here
Bike plug #1, wire #1, color: _____________
Bike plug #1, wire #2, color: _____________
Bike plug #2, wire#1, color: _____________
Bike plug #2, wire#2, color: _____________
Bike plug #2, wire#3, color: _____________
Bike plug #2, wire#4, color: _____________
So the original CDI module had two plugs?
Does the new CDI module have two plugs?
Do the plugs on the bike, fit the new CDI?
Did you alter anything to get the new module to plug into the bike?

The Red wire is probably power from the bike's ignition switch.
One or both of the Black wires are probably ground.
The Blue is most likely the trigger or pulse wire.
The larger sized CDI module (the original) is designed to be powered by the battery.
The smaller CDI module is probably for AC power (at one time I tested a few AC and DC modules). If these are connected to a DC ignition bike, smoke will appear as the DC power cooks the AC circuits, and the CDI module will be ruined. It usually does not harm the bike.
Old Mini Bike Warehouse lists a bunch of CDI modules, recognize one like yours?

yes this is what I have CDI Module for Honda Capacitive Discharge Ignition
You need to get the larger-sized, DC-powered CDI.
The original battery-powered CDI module probably has:
4 wires connected to the 4-wire plug
(2 are Ground)
(1 outputs power to the ignition coil)
(1 takes in pulses from the pulse coil on the engine)
1 wire connected to the 2-wire plug (the Red power wire)
Sounds like you need the battery-powered version.

You are quite right, my oops. Many have dual grounds, but only needs one. You did fill out that it had 3 wires on one plug, and one on the other.
OK so you have a DC-powered CDI. This was used on bikes made for very easy starting. The system generates a whopping spark at minimal cranking speed.
In contrast, it takes a rapid powerful kick to start an AC-powered CDI since the engine turning powers the ignition.
OldMiniBikes Warehouse has a 12 Volt CDI that might work:
