Powerdynamo brings new ignition & light
Electronic replacement regulator for stock 6 Volt motorcycle
dynamos voltage regulated, for negative ground only
Part number 80 50 588 03
do not use together with LED control bulbs
will this work in my XYZ bike?
|Caution: there are regulator on the market which are copies of this part and possibly made in China with the same name code R81. Those are NOT Vape/Powerdynamo parts. You can tell that by the missing logos.|
issue in the use of this regulator is the need to disactivate the
regulating resistor. (see
nearly all problems encountered with this parts, such as overvoltage or no voltage at all are a rsult of the resistor not removed.
LED charge indicator lights will not work in every case with this regulator. also it can be that they disturb regulation.
|Designated use||Replacement regulator for 6 Volts motorcycle
- negative ground (use on positive ground will destroy the part!)
- at least 4 field coils (winding packets inside dynamo housing)
- minimal resistance of field 2.5 Ohm
- maximal 16A output (~100Watts)
- will deliver 7.0 to 7.2V regulated DC
- may be used for positive or negative excited fields
positive excited field does NOT mean positive ground! this would destroy the part!
- needs battery in system, will not work without battery
- you need to eliminate stock resistor for field excitement (simplest cut wire)
this is sometimes tricky as it might be difficult to find that resistor
not seeing such a resistor does not mean there is none (or no longer!)
- operating environment -20 to +80 °C (-4 to +176 °F)
||Even the best regulator can not regulate what is not coming. Please consider that the problem might be a dead dynamo! You can not use this regulator without battery!|
|Terminals||4 push terminals 6.3mm labeled
DF- is the DF terminal for use with fields connected to minus carbon
|Dimensions||90x40x30 (with pins) see Dimensions here|
|General Installation information
||Take the stock regulator off, Make a not of the
Mount the regulator to the bike. Fix it seczurely, not only loosely as any uncontroled movement might trigger shortcircuits! It may have, but need not have ground contact on its casing, as there is a ground wire to be affixed there anyway.
Pin DF- is use for negative excited fields, Pin DF+ is use for positive excited field. If pins DF- and DF+ are confused, the unit will NOT be destroyed, but the system will not deliver current.
DF- and DF+ shall however never be connected. This will destroy the part! As it will be destroyed when used on positive ground systems or with accidentially reversed battery (even if very briefly)
For a flawless function of the regulator you need to disconnect the regulating resistor of the generator and you need to have a working 6V battery in the system
