Battery maintainer with a draw? disnt know which place to post this so I though it would be good to go in here, but my car has a draw right now to the battery and it keep draining it every 3-4 days. It’s kinda weird but I was wondering if it’ll be okay to keep a battery charger/maintainer on the battery when I’m not using the car till I found out what’s draining it. Don’t like keeping the battery unplugged from the car because then it idles really weird when I first start it up again.

no aftermarket anything. This all started happening after I took my car to a shop and got heads, cam, intake, and injectors installed. After I got it back it had weird starting issues when the car was already warm so I thought it was hot start issue with the tune so I took it to a local tuner and get it all retuned and everything and it’s to this day still doing it.

Sometimes when this happens it is due to someone hooking up an orange or red wire (always hot) to a pink circuit (keyed hot) which will allow things to draw the battery. It is most likely an easy fix but might take a while to find. Assuming the shop did not take the interior out the wiring issue is probably under the hood and possibly from the purple wire to the starter (keyed hot) touching the main red battery always hot wire. Get under the car and check the starter wiring and make sure it is on the correct connectors.

Good info right there, I know you said you had the alternator tested but it could be a bad diode, it's a one way check valve inside the alternator to keep the battery from being drained.

yeah probably gonna replace the alternator for the heck of it honestly. Pretty sure that’s not the reason as I said above this all started happening after I got my heads and cam installed but might be worth a shot

Although a bad alternator diode can lead to battery drain, their purpose is to convert (rectify) the alternating current output of the alternator to direct current for the car's electrical system - not to keep the battery from being drained. I would not replace the alternator simply because it is remotely possible that it is causing a battery drain... do some diagnostics and then fix the actual problem rather than just randomly throwing parts at it.
