generator help anybody

[joe90]

just picked this up very cheap .the problem is the power output .the motor is good and strong .it kicks out 110 as it should but it the 240 output its only kicking out about 50 v anybody any ideas thought id ask on here first.

thanks in advance

is there a switch to change from 110V to 230V?

 

[simon718]

zoomed in, looks like the switch below the voltmeter changes the voltage

the switches on the two breakers don't look like they are in the same position?

 

[joe90]

already tried it.its pushing 110 ok ,but about 50 volts in 230 mode .

 

[joe90]

my next door neighbour thinks it may be the rectifier .i dont know much about generator so any help would be great .thanks

 

[madkayaker]

if you got it B&Q take it back

 

[joe90]

i bought it from someone else because it was not working properly , is it worth getting it repaired ?i got it very cheap : )

 

[joe90]

and no its not nicked ,i bought it from a chap who ownes a secondhand shop in the town.He bought it with an ice cream van ,he then blew the engine up on the van .so he just sold everything seperatley .and the genie was part of it .

maybe but probily not. There isn't a reftifer on it as the altinator generates AC.

oooohhhh .so it sounds like the alternator could be shot

 

[madkayaker]

if it has been used at high loads for long periods of time then probably burnt the windings out for 230V. Take the cover off and just check there is no loose connections that kind of thing might be in look

As a matter of interest, will it have two 110v windings, switched in series for 220 and parallel for 110? In which case it could be the switch or any relays?

 

[madkayaker]

could be or it could be that it has multi point taps. 50V on the 230V sounds like an induced voltage so could be totally open circuit

 

[joe90]

i will take the cover off and have alook check the wires will take some pics

 

[madkayaker]

that might help.

There should be two 120v legs , with the 240v being 120v+120v, in series
The breaker, switch or coils of the bad output leg need checked.
A bad breaker is most common.
If it seems to put out full power on the 120, the diode/capacitor unit for the exciter coils is probably ok.

a pic

 

[simon718]

looks right and clean in there

 

[joe90]

thats what i thought.the whole thing dont look that old either .i paid £40 for it

 

[bawjaws]

have a look at the back of the switch board for loose cables too
