Hi there, recently my brother put my battery in my geo metro backwards ( having the best intentions) as I’m sure you know this blew quite a few fuses, I have also changed the computer, the cluster , all the relays , the ECM module & I still have the battery and check engine light on The car does run ( ok) I have tried the diagnostic port but all I’m getting is the green shift light flickering fast Any ideas I really want the car back to where it was before Dave ---

What year is this car? ---

I’d use a voltmeter to measure charging voltage at idle. Should be around 14V it sounds like the battery is not getting charged If I were you, I’d have that battery tested You might have blown the fusible link for the alternator, or the maxi fuse In fact, the low charging voltage might be the root cause of the weird problems you’re now having ---

It’s a 95 geo metro I checked the charging it’s right at 14v at idle Where is that fuse able link located , thank you so much for the help ---

I did not mention I have also replaced the alternator , the starter, and the battery Although I don’t think any of them are bad ☹ ---

The fusible link is the heavy wire that runs from the alternator to the battery. But because you have 14 volts at the battery at idle…I doubt that it is a problem. Yosemite ---

Agreed, it sounds like your battery is being charged just fine Thanks for checking the charging voltage ---

Just a thought but sometimes it takes a few starts and drives before the check engine light resets. Could that explain some of this? ---

Have you checked evey fuse. Have you read the code? Here is the procedure. [http://www.robietherobot.com/metro/errorcodes.htm](http://www.robietherobot.com/metro/errorcodes.htm)
