Hi there,

Can someone maybe explain why there are a Big Capacitor inside my instrument Pod?

I have seen it also on one or two other trikes but do not see the need for it.

It looks like the Positive from either the battery or the engine is connected to it on the one side, and on the other side is going to whatever needs power.

I want to sort out the "Kraai nes" of wires inside my pod and need to know the purpose of this capacitor.

Thanks

Martin

Helps kill radio noise. The simple generators used on the smaller engines produces charging pulses, rather than a continuous current. The battery does a fair job of damping these, but is not 100% perfect. The cap (usually) does a good job of getting rid of the rest. Remove the cap, and you will hear a continuous whine on the radio.

There's any way a whine on his radio -take it out

So if I understand correctly. On the side the battery should be connect and the other side the electronic devices and the generator directly to the Battery. There is a whole lot of wires in there which I think half of them is not being used.

What is strange is that after the capacitor I am only reading 10 - 11V

Maybe this is because of all that extra wires.

Should be mounted as close tomthe regulator as possible and rated at minimum 22,000uf at 63 volts wired between positive and negative. Dont take it out unless its blown up.

There could be many causes. It would be best to take it to a professional. A substantial voltage drop could indicate a serious issue (either a poor connection, or too much current for the wire being used), which may also be a fire risk.

The Cap will not bring the volts down, it is not a resistor, it evens the current and absorbs some of the alternator noise. It is connected to the bat pos and GND and like zulu said, the 22000uf will do the trick. Have the wiring checked by someone who knows what he is doing or read the manuals or do both.
