Push Start Acting Weird.
 

So I just installed a new turbo with some gauges on my 2015 auto BRZ and now the car won't start. This happened today right after I installed my gauges. Whenever I press the start button, regardless of whether or not the brake pedal is pressed, the gauge cluster acts as if the car is being turned on even though it isn't. This happens with the brake pushed down as well. The car also beeps thinking the door is open when in reality, the door is shut. The infotainment system doesn't even turn on anymore. I've checked the fuses and none of them seem to be blown. This all happened today after I installed the gauges, the car was working great before with the turbo installed. Any suggestions?

Will it start if you disconnect the gauges? What gauges did you install?

Interesting. So an additional problem I had was my headlight stock literally wouldn't work and disconnecting the power to gauges seemed to fix my door beeping and my headlights. However, my engine still didn't turn on. Going into accessory mode seems to bug my gauge cluster into thinking my car is turning on.

Sounds like some sort of installation issue.

I'm an idiot. Apparently the battery was dead. Guessing this happened since I had 2 add-a-fuses with 4 15 amp fuses for the gauges and that was just too much. Going to switch some fuses with lower amps.

fuses don't work that way...

Welp, like ol @soundman98 said, "fuses don't work that way".

If you have 4 15 amp fuses in your dash light circuit, you might as wire them direct for all the good they would do.

I reckon a 10 amp fuse should regulate all of them OK.

I'm thinking you may consider taking your car into a auto electrical shop and have them straighten it out.

Also, you should find out what drained the battery and fix that situation.

Did you hear about the ol boy from Washington that was out hunting with his buddy in his old pickup truck. It was getting dark and the headlights wouldn't work. His buddy suggested he check the fuse. He did, found out it blew. His buddy suggested he insert a .22 shell in the fuse slot, so he did.

About 2 miles down the road, a shot rang out and the .22 round hit his buddy in the leg. His buddy shouted out - I meant for you to put a spent shell casing in the fuse slot!

Haha! Thanks for the hospitality! Yeah I was running the gauges and and all the electrical systems in my car for around an hour which is probably why. Well, that and the fact she's been on jack stands for the past week and a half. I emailed Glowshift whom I purchased the gauges from and they recommended a 5 amp fuse and a 15 for the add-a-fuse slots. Odd how that wasn't on the instructions so I didn't know.

Yeah, I'm really new to electrical stuff so I really don't know haha, thanks though! So I'm pretty sure my battery just simply died from being left untouched for almost a couple weeks along with the fact my car was on accessory power for over an hour.

fuses are a limiting device. think of it like a cop with a radar gun. if the speed limit is 15mph, there is nothing limiting you from going any speed from 0-15mph, but anything over that limit, the cop/fuse will put a stop to the 'fun'.

typically, one should fuse a device for just over what it needs. this is done so that there is an allowable margin of error in power draw(if it draws a little more than it's supposed to, NBD), but if something goes wrong and the device starts drawing significantly more power, the fuse is there to stop it before the device can start on fire and cause more significant problems.

Well, they probably were, but the print was soo small you couldn't read it with the unaided eye. - :iono:

Yes try some 1 amp fuses they use a lot less. If your battery still goes dead just keep putting lower ones in. Try 1/2 or see if you can find 1/4 amp. Soon your battery will never go dead!
