Hi fella's, I have this brushless 24v alternator and i would like to get another volt out of it, it puts out 28.6v and i would like to fit it with a circuit that i could switch to every now and then to get 29.5v.
In the past I have achieved this with alternators that have slip rings by switching to a circuit that used 2 diodes in series to the regulator battery voltage sense terminal, this gives a lower voltage to trick the regulator into pumping more juice into the rotor winding and uping the output voltage.
This brushless alternator self energizes at about 1500 rpm and nothing I do with the diodes on the battery sense or the switch terminals on the regulator makes any difference, it doesn't even seem to matter whether any power is connected or not, except at low RPM power to the reg does excite the alternator.
Has anyone here got any clues as to being able achieve this??????
The load on the alternator adjusts the engine RPM to suit the load, there is still some work to do but it is working as it should, here are some pics of the alternator and where i am up to. This gen is actually Mk2, the first alternator I used had stuffed diodes so i had to modify things a bit to accommodate a slightly larger alternator....
