I’m new to the form. Not sure if I did the list right the last time but I’ll try again. I got the catalytic converter removed last year thinking that’s what where it was coming from. I was driving and the car quit. I could still smell the rottin egg smell and then I noticed the battery as swelled. I replaced the the icm battery and new coil. Next day same thing. I replaced the icm and battery. I took a volt meter to see if it was over charging but I didn’t notice it was by idiling turning a/c on and checking it like that. But something is making it over charge while I’m driving I’m thinking and burning i icm out. I did put in a new coil as well. So I’m thinking it could be the alternator I guess. But not too sure. Any thoughts ? Thanks Rennie

Im just gonna beat everyone to the punch here.
Get a multimeter, they are only a couple of bucks. Start the car and find out what voltage is pumping out. No point in throwing a 200$ alternator at a problem until you know for sure you actually have a issue there.
Keep us posted

I believe I did say that I checked the alternator in my post. So I’m no sure if it happens when I’m driving the car that it might be over charging then.

What's the voltage reading when the engine is revved to 3000 or 4000 RPM?

1237 with lights on and A/c on as well. Don’t change much at idle

12.37v.... and you think it's overcharging?  That doesn't make any sense. With the engine running, the alternator should be supplying the battery with 14.6v
What's the battery voltage with the engine not running and nothing turned on?[This message has been edited by Patrick (edited 05-23-2023).]

I was thinking that the first time cause the battery was bulged , unless that happened in the winter. The other battery I bought just went dead . When I drive the second time with the new battery check engine light came on little longer car quit. That battery was low on volts and the icm was burnt out again.
