Hello Guys,

I think I blew the fuse in the accessory socket (cigarette lighter adapter) and need to know where to look to replace it. I believe there is a fuse box in the passenger foot well.

I have the shop manual, but can't find a diagram or listing of the fuses there. Can someone point me in the right direction or at least tell me which fuse is for the accessory socket? Alternatively, if someone has a copy of the fuse box diagram they can send me, that would be fine too.

Thanks in advance.

OK. I found the diagrams and layout in the owner's manual.

Just FYI, the fuse for the accessory socket is located in the Power Distribution box under the hood (trunk) and it is #22 named "Power Point".

It is a 20A mini-fuse.

Thanks!

Be glad you did not have to get into the fuse box with black goo holding on the plastic sheeting.

Good deal ... so what happened? Draw too much current?

I was changing the battery and didn't want to lose my ECM mapped values so I hooked up an external power supply to the accessory port. Turns out the adapter I bought off ebay had the polarity reversed! That'll teach me.

Once I replaced the fuse everything seemed to be OK. I spent the rest of day cleaning the battery box and checking grounds.

By the way the battery I'm installing is a custom designed lithium battery which should last the life of the car. I'll install it today. My design has worked fine in my old Honda Pilot test vehicle (3.5 liter V6) for the last year, but this will be the first time cranking a V8. Finger crossed.

Thanks!

"...Life of the car"? Selling early?

LOL, no, I do not plan on selling my GT. I love the car too much.

I was just tired of dealing with lead batteries that have a tendency to sulfate when discharged and even when on a trickle charger, they have short lifespans. Even the sealed Optima I'm replacing corroded the negative terminal over time.

I bought the car new and I've had it for 15 years. In that time I've purchased two or three batteries, which isn't bad for a car that is not a daily driver. I just wanted something that truly is "no maintenance" (other than putting it on a trickle charger every now and then).

By the way, I installed the lithium battery and it works! I'll post a photo after my in-car testing is complete.
