Alternater has 4 wires white andbrown/w is plug in white wire goes on post have has nut to hold on old altrnator had capasitor on it weredoes black and capasiter wire up to thanks bob

Incorrect alternator. There is no battery regulation working in the new one.

My diagram shows
1. Black/white
2. Red/white
3. Red
4. Brown
I hope this helps. Take care.

On your starter is a small post that activates the starter. the wire comes from the IGN Switch.. when you turn the key power comes down this wire and powers them solonide to engage the starter,

If I understand your assessment then yes. One wire (black/hot) is interrupted by the switch, and the other (white/neutral) normally passes the switch un-cut. FYI - any chance you get to ground a device should be seized; as this will help reduce shock risks associated with direct faults (wires touching stuff they shouldn't).

the one with the thin white wire goes to the thin black. The thick black is the pump ground

some times overloading the small wires will do that ,check the amps and voltage,other wires may have a bad conection and the juice will go the shortest way,check the connections on the main ground and power wires,find the hotest spots where the problem resides as weak wire or a bad contact,you may want to double the hot ones to check

The easiest way is to check the speakers themselves as manufacturers tend to change colors of speakers at a whim. Usualy though you will have 8 wires (4 front & 4 rear) paired in colours (white goes with white+black stripe(stripe is possative on speaker))etc.
Not knowing the cars electrics I can't be more specific.(I live in UK so don't know that much about U.S. cars)

Yes the White wire is the reason. It goes to the Internal Regulator.
As you view the connector that plugs into your alternator, look at where the lock tab is.
Lock tab on TOP. The Black wire goes to the Left side. The White wire goes to the Right side.

The Black wire, ties into the Red wire down in the wire loom. (The Red wire goes to the starter solenoid, and this is connected straight to the battery. This is why the Red, AND the Black wire, are both Hot wires)

The White wire goes through the bulkhead wire loom, and to the bulkhead connector.

(Down under the steering shaft, and on the firewall, you'll see a rectangular Black box shape, with a Bunch of wires, coming into it from the engine compartment. The bulkhead connector is two pieces. Following it through the firewall, the other side of it is the fuse panel)

Where the White wire connects in the fuse panel,
it should go straight to the ACC fuse. (Accessory)

it could be a lot of problems from the battery, battery cabals to the alternater. check to see if the battery post are caroted and needs cleaning. if sow remove the battery cables off of the battery then you can use baking soda and water which will help remove the corotion and nutrliz the acid on the battery posts. then clean the battery post and battery cabel clamps with a wire brush. if it is not the battery post take the car to autozone and have them see if thay can test the battery and altrnater on the car to see if ether one of them needs to be replaced

Unfortunately the Honda alternator is regulated by the ECU, which allows the ECU to intelligently reduce alternator engine loading to improve fuel consumption. The intelligent system uses an electrical load detector (ELD) located near the battery to control the alternator output voltage. A two wire alternator has an inbuilt regulator that will always generate the required charging voltage. When a battery is fully charged and the electrical loading is low there is no need for generating the charging voltage, in this situation the honda alternator will reduce the output voltage to reduce engine loading, hence improved fuel economy.
