Question about 2000 Chrysler Concorde
There is intermittent battery drain causing it not to start. Dealership does not believe it i caused by caroded wires to reading lights, trunk. undserhood, or glove compartment
The alternator has semiconductor diodes to change the AC it generates into DC for charging and operation of the electrical system.
These diodes can fail 'a little' meaning that their reverse resistance falls below its normal level, which is very high and will only allow a few microamps to flow, a level of discharge lower than that your other electronics such as clock and digital odometer functions draw and insignificant to the battery's health.
If you have a multimeter with a 10 Amp range, something very common even on the cheapest digitals via a separate unfused jack, you can remove your negative battery clamp, insert the meter (set for that separate range), black lead on the clamp, red on the battery terminal, and measure current draw with the engine off.
Note: Fasten one lead firmly and the other, tap only until you can see whether the drain is greater than 10 Amps. If is much greater, it will destroy the meter bbut briefly connecting shouldn't hurt it.
These meters can be had in auto parts stores, Radio Shack (in the US) or other electronic suppliers. If in the US, you might check for Harbor Freight tool stores in your area; I have bought several of these handy meters for $3 US there.
