The WRX914 has a battery drain. Pulled all fuses, relays, grounds. No change.
I ended up at the generator? I pulled the two big white wires off (coming from the battery) and removed the plug with two small wires. The pole that the two big wires went to has continuity to ground. Is this telling me that the $200 generator is bad? |

The load I read on the multimeter with everything hooked up and with the dial on Rx10, the needle reads 5. I don't know, is that a lot?
Disconnect the alternator and it reads about 30. Where are you taking this reading? It is 50 ohms and 300 ohms Rx10, so multiply the reading by 10. Quite a difference, but I need to know where and what leads were where. Black lead to ground, red lead to ?. Do this reading with the neg. battery cable disconnected. With everything off, this reading should be high as in lots of ohms. The more the better. 50 ohms to ground will give you 240 miliamps ( 12 volts/50 ohms=0.24 amps) 300 gives you 12/300=0.04 amps). Do you have a clock hooked up? A clock should not run the battery down, however it is good to know when taking readings. Sounds like maybe you have a drain in the alternator. Is it very dirty? Oil and dirt can combine to form resistance and coat parts in the alternator until you get a path for current to flow, however small. Tomorrow should give you some answers, Tom |
