Default Could this be something other than CPS or RCM?

Hi all!

I just ordered a Crank Shaft Position Sensor, and in the middle of re-soldering my Relay Control Module.

While I was on the road my car died, and would not turn on. So immediately I thought it was the crank shaft position sensor but I just replaced mine this year.. So I thought otherwise, leading me to get a new battery that did not solve the problem...

It seems like my battery just gets drained.. And the lights that come on are "BAS/ESP", "ABS", "Battery", and the red "Air bag" looking icon..

Before my car died all these lights came on...

So the question I have is, do you guys think it's the alternator? Or something other than the RCM or CPS that's draining the battery?

I can get my car to turn on and idle for 3 minutes before the engine starts shaking and the electrical stops working.

Always appreciate the advice guys,

Best Regards,

- Gdrag

Easy alternator test :
If you don't have a voltmeter/multimeter, go get a cheap one from Radio Shack or WallyWorld. ( you can also get a digital voltage meter that plugs in the lighter socket from most any auto parts store ) or :
http://www.ebay.com/itm/LED-Display-...ht_3533wt_1397

I just ordered 4 of those, total was $10.86

1. Measure between battery terminals with car off : should be 12.0 - 12.7 volts.
2. Start it up, should now be around 14.7 Volts.

if 1. not OK - then charge the battery and try again.
if 2. not OK, then alternator issues.
