"FUSE" flashing at startup/battery drain

2001 ACR w/ac, has factory am/fm 6 disc changer.

When I get it started, the dash makes a tone, and "FUSE" flashes on the gage cluster. Battery won't hold a charge (have had 2 different batteries in car). Ever since I re-installed the radio/cd player, this has been happening.

What is causing the FUSE flashing?

Battery held a charge before radio was re-installed.

I will uninstall the radio electrical within the next 2 days to see if the issue goes away, and if the battery will hold a charge after that. If that doesn't work, I have no idea where to look (no good at electrical stuff).

Any one have any ideas? Please PM, post here, or email me (below in sig).

Thank you in advance!

If the battery is low, it will flash fuse. It may be the head unit is draining the battery for some reason. I would do what you said, unhook the audio, and see what happens, or do an ignition off draw, to see what is draining the battery.

You will need a multimeter with an ammeter to check tho. Unhook the positive cable from either the battery, or PDC and check draw across the cable to the terminal. There should be some, but not more than an amp or so I would think. I really don't know what normal IOD is.

To check the alternator for a semi short to ground, leave the PDC unhooked, and go from the battery terminal to the cable. (Cable removed from battery.) This has happened to me on another car... corrosion is a bitch. :lol:

These cars usually flash fuse when the battery is stone dead beyond any charging or jumping. My SRT even turned on the low side fan, and kept the left turn signal stuck on also.

Thank you both for your input :thumbup:


Radio is disconnected, and the battery is on the charger. We'll see what happens.

Gotta get this car road worthy again so I stop driving the NYG and get it sold!

*update*

All is good. Turns out it was the trunk light staying on, but not all the time (was drawing 600ma). Would come on by itself, and turn off by itself, all at random. Weird...
Took the wire off of the trunk latch, and it stopped doing it, so I guess I'll grab a latch next trip to the salvage yard.

Oh, and the NYG is as good as sold - took a deposit on it last nite :thumbup: :(
Glad cuz I need the money for a new furnace, but sad to see it go.

Was the trunk light the final root cause of the problem coupled with the battery needing to be charged?

I pulled the bulb to solve the problem. Never had a trunk light before so I don't need one now.

I had this same problem, I had been slamming my trunk to get the light to turn off for like 3 months then I back into someone and its all good now lol.
