EQUALIZING TIME CYCLE:
The software in the new Digital Regulator automatically calculates the equalizing time cycle every time the
engine is started. This will range between 1-12 hours depending on the rise time between engine on and time to
reach 14 volts; this will be different every time the engine is started, and varies from battery type setting . The
internal computer software will look after this function.
The cables positions are marked on fig 4 and 5
a: Yellow: This is a simple ignition feed and should be connected to the ignition switch or any 12/24 volt supply
which is live when the engine is running i.e. if there is no ignition switch then any good 12 volt supply will do
with a simple on/off toggle switch to switch the unit on or off, i.e. when the engine starts switch this cable on,
and when the engine stops switch this off. extend as long as you want
b: White:(Previously Green - changed due to new
C.E regulations) The white is the alternator control cable, and
should be connected to the field wire you fitted to the alternator earlier. This wire can be connected or
disconnected with the alternator running, there may be cases where the Advanced Regulator needs to be switched
off (i.e. small engine on a boat and a fast current) the Regulator has been known to knock off 1.5 knots of small
boats with a 10-15 hp engine, however, most people usually connect and disconnect this cable (out of curiosity)
to see the difference the Advanced Regulator makes to their system (with the Pro Digital, this unit can be
switched on and off using the remote control). Extend as little as possible
c: Brown: The brown goes to the D+ on the back of the alternator, this is the small cable which is usually marked
on the alternator case as “D+” or “ING” or “ L” or “61” it is the cable which feeds the warning light on the dash.
Connect the brown to the same terminal leaving the existing cable in place
d:Blacks x 2: There are two black cables, these cables, if extended must be extended as two cables and
connected to the alternator B- (B negative) or to the alternator case. If these wires are extended then please
extend as 2 x separate wires and join at the negative at the alternator, I know this sounds stupid but trust me.
Extend a little as possible
i: Black/white stripe: This is a new cable, which connects to the main domestic battery bank negative rail. This
cable measures the negative at the battery banks, and checks it to the true negative at the alternator and ensures
there is not to big a voltage drop in the negative cables. Any voltage drop in excess of 1.5 volts will trigger an
alarm and shut down the Advanced Regulator on high negative volt trip. extend as long as you want
j: Red: The red is the sense wire, wherever it is placed on the Regulator and will regulate the voltage of that
spot, therefore, it is important that the end of the red cable and the alternator must never be isolated when the
engine is running.
The position of the red wire varies depending on what your charging system is:
Split charge diode: If your alternator charging circuit has a split charge diode fitted, position the sense on the
battery side of the diode, on the side with the largest battery bank, (in the event of only two identical batteries
either side will do).
Split charge relays: Same as above, however be warned, most low cost relays in the marine industry are approx
25 mm cubed, these relays may have been good enough for your old poor charging system, but when an
Advanced Regulator is used do not be surprised if after a short period of time the relay melts. Only use good
relays.
Rotary switch: Most yachts are fitted with a rotary switch, i.e. a switch with bat 1, bat 2, and both. With this type
of charging system, position the sense on the back of the switch on the common point, remember that the only
batteries to be charged are then dictated by you i.e. 1 or 2 or both. Due to the limitations and the constant
changing of the switch, it would be my personal recommendation that, at a later date, you separate the charge line
from the common starter feed and charge through a split charge diode.
Boats that have their bow thrusters positioned some distance away from the two main battery banks should place
the battery sense wire (red) at the main battery bank and not at the bow thrusters. This is because the increase in
battery voltage caused by the excessive distance between the battery banks can be too much for the main battery
to deal with. The bow thrusters' battery will still benefit from the Advanced Regulator even if the sense wire is
placed at the main battery bank.
Special vehicles: with no split system, connect the sense to the vehicle battery positive. extend as long as you
want
Testing the system:
Start the engine up as usual, the green boost light and the float light (yellow or green depending on booster
settings) should be on,( the green boost light will flash for 2 mins on start up to show the slow start, this is to
reduce belt slip ) the battery voltage should be measured to ensure the voltage works its way up to 14.4/14.8
depending on its settings. This could take between 1 minute and many hours depending on the battery bank size.
The voltage may vary slightly from alternator ie +/- 0.1 of a volt,.
some modern alternators have no D+
in this case connect to the B+ (the main positive output). extend as little as possible
DO NOT ALTER THE FACTORY
regulator.
Remember to replace the old regulator back into the alternator do not leave it out.
1) By now you should have completed the pre installation section, I will take you through the Regulator set
up and also explain what you are doing.
2) Remove the Regulator lid, inside you will see the circuit board with a 2 pin dip switch and a large fuse: See fig
3 , i = large fuse and h = dip switch
Battery Type: Identify the small 2-pin dip switch, and set the battery type as per your battery type, explained
earlier . the settings are on fig 1 , and also on the metal lid of the Advanced Regulator.
Alternator Type: You should have established what the alternator field type is by now , it should be a negative
or positive field control, ensure you have the correct information.
To set the alternator type, see fig 4. for neg, the fuse should be inboard of the edge of the case, if a pos unit then it
should be beside the case edge
There is a standard automotive 5 amp fuse in the Regulator, there are three legs which will hold that fuse, the fuse
should come standard set to the neg position. In order to convert the Regulator to a pos remove the fuse and
reposition it in the other slot. The
and pos positions are clearly marked on the printed circuit board
drawing and on the instructions fig 4.
Set Up Advanced Regulator Before Installation
negative
WARNING: Under no circumstances use the Regulator on gel or sealed batteries if the battery type L.E.D is
yellow when on this will permentelly damage the batteries.
Failure to get this right will result in damage to the advanced regulator
and maybe the alternator's standard regulator.
