Acc. power interrupts when starting engine. Any way around this?

So i have a dash cam and radar detector and aftermarket head unit. I shut off the engine and continue listening to music while i wait. And then when i go to start the jeep back up all the electronics re-start when the engine fires up.

Is there anyway to keep the accessories running while the key is turned to start the engine?

Maybe a mod by installing a capacitor in the acc. circuit?

I don't think there is... and if there is, not sure I would want it.

Its all about amp draws and blowing fuses. your battery can only supply so many amps at one time before it gives out. Your battery might not be able to run your radio, fans, lights, engine computer, dc outlet etc etc etc... whatever options you have... and still turn over the engine. It cuts out for a reason, not because the mfg doesn't want you to listen to tunes as the car starts.

I realize that, but i've got an optima yellow top battery in the jeep. I've got the yellow top in my truck as well and it doesn't cut out the acc.while it's turning the engine.

I'm guessing a super capacitor to hold the charge for couple of seconds.

Yeah that battery is crap and will fail shortly.Nothing you can do as it's how the ignition switch is wired,it cuts all non essential loads to provide the most cranking power to start the engine.

Many KK owners have hard wired a second acc port AKA: cig lighter and wired it direct to the battery.
