Tohatsu 9.8 4-stroke Rectifier install

[J-Man]

Does anyone have experience with installing a rectifier on a 4-stroke? I did one this weekend and engine starts fine, but as soon as I connect the rectifier to a battery to charge it. The engine dies immediately, not sure why that would be. Thoughts?

Make sure all connections are made and double check the grounding

If I disconnect the battery the system runs fine but as soon as I put the battery in line it's like hitting the kill switch.

Like the rectifier is drawing all the current to charge the battery so the CDI gets nothing.

You should be able to check the component out with an ohm meter easy enough.

Thanks got it sorted, the coil is only putting out 3.4 amps, so not enough to run the CDI and a rectifier. The rectifier draw is to large, so I have to buy an alternator kit from Tohatsu which is basically a 2 coil deal and remove the single coil. That will boost the amps up to fix the issue.
