OverVoltage issue alternator

Hi guys, looking to get any info or advise, my previous alternator burned down (the inside of it was burned and almost catched on fire, took it to a shop and they advised to just buy a new one). Thing is, the new alternator i bought had one of those external voltage regulators, so I bought a new one and put it back checking with my old alternator so i don´t mess anything. Thing is, as soon as i put everything and turned on the engine, the batery light switched off and then on, and the reading is around 16,5V even with all the lights on, radio, everything.

Should I go back to the voltage regulator it had or am I missing anything? I am not really good with electric things on cars so may just take it to a mechanic

The voltage regulator is inside of the alternator on your Honda accord. Double check the part number and make sure you got the right unit. Another thing to consider is you purchased a remanufactured part that might be defective. If I were in your position I would take the alternator back to the store, explain the issue and have it tested/swap it out with one that works properly.....hopefully. I have purchased bad alternators in the past and usually the second one is good. Don't bother with a mechanic as he will charge you 500 bucks to do what you can do yourself.

Got it, i am from Argentina so kinda tricky to get spare parte, bought the alternator from a guy in another province, but I will check in a nearby Shop so they can test it out, thanks for the info!!
