New member singer 320 alternator question

New member here, my apologies if i don't know what I'm doing, I appreciate all the help.
I recently bought a 2015 2wd 4.0 4 dr Tacoma. It's loaded with outdated sound system all occupying the back seat, with second Lithium batteries, 2 midrange amps, 1 big amp to power a huge subwoofer . Decided to remove all the sound equipment , power cables and batteries to make room for a back seat so that I can use to haul my family.

By the way I remove the main Lithium battery, replace with a regular interstate battery.

There is a Singer alternator that powers all this equipment. I also noticed that it has a big 3 upgrade with 0-gauge OFC cable.

Looking from the bottom of the truck is has a Singer either 3530-3520 or 1520-3520 model
alternator.

My question is, is it wise to replace this alternator with the OEM alternator or I can leave it there without causing any harm to the electronics or mechanicals on the truck?

What is the pros and cons of leaving it.

I would like not to spend money to buy another one if I can still safely use the singer alternator.

Any comments would be appreciated.

I wrote to Singer company, but I got no response.

Thanks a lot in advance.

 

You are fine leaving the alt in place. It only provides the extra power as requested by the electrical components. It may draw a bit more power from the engine but if there are no electrical bugs, I would leave it alone.
If you are in southern CA, you can have my oem alt. I installed a BnR 200-amp alt and they didnt require a core. I replaced the brushes and kept it as backup. Six years, or so, later, the BnR is holding up well and I am willing to give away the oem alt to someone that needs it.

 

Thanks for the response.
I'm too scared to drive this truck far thinking it might blow up on me with the big alternator. LOL.
Do you think based on the label of the alternator, is it 320 amps ?
Toyota OEM will cost me $350, which is too much for me right now.

 

That’s not how alternators works.
They do not continuously charge.
They turn on and off on their own.

New vehicles even have a variable charge rate.

You are just fine leaving it in the truck.
I always recommend leaving things alone if they are working.
Parts quality today is awful. You might actually create a problem “fixing” a nonexistent problem
