| Hasn't anypone done any measuring to identify the amount of battery drain? Or is everyone guessing? First of all, with everyting off includig the engine, measure the amount of current drain at the battery terminals. There can be a very samll anount taken by the clock and 'keep alive' memory. A security system may take the most. The draw should be very samll, in the millamp ramge. A good repair manual may have the number, but these small drains are seldom discussed in the maintence manual if it is insignificent to begin with. Measuring the current draw may help identify the source. Maybe a small lamp is lighted. Hidden lamps are glove box, trunk lid, and under hood lamp. Some auto have a 'reading lamp' located in the rear passenger compartment. I had one that was on the wall above the rear seat. Its switch was not obvious. It was turned on by rotating the fixture. Once on, this lamp stays on even after the doors are shut and the suto vacated. It is manually operated. If a search of car turns up nothing, then its time to begin tracing where the leak is at. This could be a terdious process since it could anywhere or anything especially if the car has been lightening struck as stated above. If you are certain the damage was by lightening, it may be covered as storm damage by your insurnace. Check your policy. I know of one case where a Ford Van was fried by lightening. Many components were ruined including the engine controller (computer). The shop decided to replace the entire wiring harnesses including some lamp sockets. This seemed expensive, but the cost was on par with paying a technician to track down all damages, and then it could not be assured that everthing would be found. But before going the drastic route of complete replacement, try to ascertain for sure the cause of the damage. Did someone do a jump start and momentarily reverse the jumper cables? One or more alternator diodes could spoiled, for example. |
