It's in manual range mode..:wow: so it seems like it's picking up the current from the air,magnetic field I should say,anyway I tried using the analog one and it's showing AC current present,but it's not an accurate reading though....

It's probably in auto-range. I'd manually select a range if you can.

I have charged the battery for 2 nights in row @ 2amps,for a week and a half no problems whatsoever,obviously knocking the wood!

IF This persists try and pull the fuse in the glove compartment for the telephone even if you dont have one
this worked for me and have had no problems since it seems to reset something but what i dont know:dunno:

Pulled out fuse #74 last night,because I started to notice that my battery started to get lower and lower every day.
Well,it seems that i am due for another draw test,but properly done one,and now I am ready.
Will post the results.
Thank you guys....
I am gonna find the Gremlin if there's any.:taz:

In this case,If the fan is blowing....how long would a battery last ,whilst the car is parked before it gets discharged to the extent that it wont start the car?:thumbup:
I say this because mine is also blowing with ignition off and car awake!I havent checked whether fan goes off when car goes to sleep,since I have to stay inside that car for 20 mins or so....
Battery currently lasts about 1 1/2 week before the starter hesitates but still starts!

I actually replaced the heater resistor(hedgehog plug)and the next morning battery flat again but then noticed that the phone wasn't working so went to the glove box and pulled the fuses with the telephone marked on took the car for a 5 mile run, the next day started no problems and the telephone back in full working order with all phone numbers still in the memory that was 9 weeks ago and never had a problem since touch wood
hope remember to replace the fuse within 30 seconds as if it was the problem it will have reset itself within that time
this helps rob:thumbup:

Thanks Rob.You replaced the FSR and that didnt solve it!Did you also hear the very faint noise fan and was the noise still present when you replaced the FSR?
I shall check the phone fuse,like you said:thumbup:

What you're describing is the Climate Control's internal fan,it's a tiny one behind the left tiny grill and it stays on until X falls to sleep,exactly 16 min.
Keep in mind that you don't need to sit in the car while waiting for it to sleep,even if the door is open X is gonna sleep if there's no motion present in the cabin,if so it will take longer,but once it's asleep even if you wake it up with some motion it's gonna go to deep sleep mode within 30 seconds.

Thanks for the information!Is the fan you referring the same fan that some members here are saying that should be off with ignition off and that its a FSR issue?
I think the faint noise I am hearing is from the right side and on the same side of the FSR.
Since I dont have to sit in the car and await for it to go to sleep,I will check tomorrow if the fan does go off.Thanks again for the tip:thumbup:

Is the fan you're hearing the tiny little fan inside the vent on the ac control panel face plate? Or is it the main ac/heater blower fan that blows the air you feel out the vents. Big difference there. But pulling the FSR out and looking at it can tell you if it is good or not, the old ones have a few big conical spiked for heat sinke while the new sytle ones have numerous thin straight pins as a heat sink.
