Anyone know what the factory alternator on a '90 Mitsubishi Eclipse should put out -- both with and without load? Thanks in advance. Fred volts or amps and at what temp? \ > Anyone know what the factory alternator on a '90 Mitsubishi Eclipse should > put out -- both with and without load? > > Thanks in advance. > > Fred Any info would be helpful.

I would still like to know if this is real world or not, since other repair shops say 16A is required under load. > Any info would be helpful. > Volts and amps cold (70 deg F) or up to engine temperature.

I should have said it puts out 14V under load - not amps. > What are you talking about? I would think that a 65A(mp) alternator should > be able to put out 65 amps if needed under "load"...

According to the SM at -4 degrees F the output voltage should be between 14.2 and 15.4 volts At +178 degrees F it should be between 13.1 and 14.5 volts. The current output for a 65 Amp alternator is (according to the manual) minimum 45.5 Amps. The regulator has a sense wire that runs directly from the battery, if the voltage drops below 13.9 volts (at 68 degrees), the regulator turns on the alternator to charge the battery. At 14.9 volts the regulator turns off the alternator, until the voltage drops below 13.9 volts. Ray > Thanks Bob.... I should have said it puts out 14V under load - not > amps.

That's a great help. > I just went through this with my sons 91 Laser. > [quoted text clipped - 43 lines] > >> >> > > > >> >> > > Fred The usual test I do is measure the battery voltage with the motor off then start the car and measure the voltage with the engine running. If the alternator is working you should see a slightly higher voltage with the engine running and/or revving. If the voltage is same as before and slowly dropping, you have a problem.
