Have a 2005 Crossfire Roadster with 9,000 km. Have a constant battery drain of 3.47 amps. So far have isolated the issue as being from the 200 amp fuse ( in the small box next to battery) to one of the 3 fuse panels in the car. I am assuming this is correct since I have removed all the smaller fuses from the 3 fuse blocks, that being the RCM plus the larger fuse box in the engine compartment driver side, as well all fuses in the panel on dash (driver side). In addition have taken the RCM apart - all contacts are open ( looks brand new). On a side note removed the cables from the alternator and starter. Still have DC voltage drain.
Obviously a short somewhere that is not tripping a fuse, but since I have removed all fuses (did this twice) after the 200 amp fuse, concluding that the fault must lie somewhere after the 200 amp and any one of the 3 additional fuse panels. Any ideas would be greatly appreciated.
Thought -is there a DC tool that you can hold against a wire to see if current is flowing? I know there is for AC.
- locating an electrical schematic would really be helpful.
There are two locations where 12 volts is available 24/7 with the key out of the ignition switch, is it possible that a previous owner has fitted an accessory that is drawing the amps all the time for some reason?
One location is at a post at the back of the underwood fuse panel and the other is the red wire I think, at the radio.
Have you studied the wiring diagrams in the Service Manual?
