Help needed ASAP.............please

[gglavin]

were is the voltage regulator on the ep91?

any help appreciated lads

 

[weeJohn]

Its part of the alternator if its the charging one you are talking about.

 

[gglavin]

yeah thanks mate, having this problem, battery not charging at all, checked everything, altenator good, battery good, can not find the issue at all.

 

[starletburkie]

try change the altenator

 

[gglavin]

try change the altenator

iv done it lad already its definetly more complicated than that. the altenator is making the voltage just not charging battery doesnt matter what alenator i put in

 

[starletburkie]

you sure the bat isnt just fucked man?

 

[weeJohn]

What voltage are you reading on the 2 battery terminals with the engine running and engine off?

 

[AdamB]

Hows the cable looking? Might be earthing out somewhere on the body or have too much resistance.

 

[gglavin]

battery is 100% and new

11.5 voltage on the battery and same when car started should be up to at least 12.5 - 14 volts when started.

im tinking it might be the cable corrosion

 

[dac69er]

with the car running, what voltage is the alternator putting out at the actual terminal of the alternator?

 

[Franza1]

did you check your earths?

Have you actually measured it?

 

[corofin12345]

if battery is ok it must be a break or bad earth from alternator to battery

 

[gglavin]

with the car running, what voltage is the alternator putting out at the actual terminal of the alternator?

25-26 volts

 

[gglavin]

Have you actually measured it?

yeah, got my mate he works on aircraft to look it over, cant understand why it wont charge hes checked everything

25-26 volts

Seriously?! That's almost double the normal output voltage of the alternator. I'd be glad that, for whatever reason, that sort of voltage isn't getting to the battery terminals.

Does the battery light on the dash stay on when the engine is running?

Have you checked the voltage drop with the engine running, between the positive battery terminal and the B terminal of the alternator? Also between the negative battery terminal and the metal case of the alternator? Were both readings less than 0.2v?

With the negative battery terminal disconnected, have you got continuity with no resistance between the positive battery terminal and the B terminal of the alternator?

 

[weeJohn]

25-26 volts

You might need someone who knows the difference between ac and dc voltage to have a look at it.

well thats probably me then i was looking at the meter, he just said that the altenator is perfect, the battery is perfect. he done a load of tests not quite sure what he done but he was scratching his head afterwards. dunno lads

no battery light on, i just let him at it as i am not quite sure myself. he performed checks, il pass it on to him anyway, cheers mate

Alternator fuse /wiring ok in passenger side engine fuse box?
