53K ohm between Batt terminal abd chassis on my IC regulated alternator

**CHB** · 28-06-2006, 10:09 AM

just rewired all the wirings for my 3TC.. before i hooked up the terminal to battery, i measured the resistance between +ve Battery and -negative of terminal, i found that i only have 53K ohm.. this is weird..
i tried to trace down the problem and found that its from my alternator Batt terminal. i can't found any short to the chassis on it.. this alternator is brand new and it is internally regulated type..it functiob properly b4 i rewire my car..
any clues about this?

53K ohm is quite a lot.

Prob just due to the decoupling caps in the regulator?

there shouldn't any problem for the leakage current when i switch my ignition off isn't it?

Is that measurement taken with the battery connected?

If so it is prbly BS. Try taking a reading without the battery connected...voltage when you are trying to measure resistance will stuff the reading generally as mulitmeters inject a very small voltage / current and measure the voltage drop accross the two lead to calculate the resistance, if there is a voltage anyway...

the battery is disconnected for sure.. the resistance is measured over an unconnected alternator with respect to chassis ground..

Why are you measuring the resistance anyway?

53KOhm, or 53,000Ohm, with 12V gives around 0.2mA (0.0002A), which has no consequences whatsoever.

Is something not functioning properly right now?

im with mos, the test you have done serves no purpose and the resistance is irrelivant

erm.. i just wanna make sure that i didn't misconnect some wires to ground.. yesterday after back from office, i measured it again... and now is Open Loop.. weird huh..
