Wiring Diagram, Light Switch Australia Print Socket 2 Switches E Gang - The mower's strength enter is a hundred and twenty volts ac "preferred household strength". The ac-dc conversion is done thru the usage of a bridge rectifier, that is genuinely four diodes stuffed right into a box. The rectifier used in maximum of those mowers is in an mb or gbpc package, having four "faston" connectors for the wiring and a single screw hollow inside the center for mounting to a heatsink. The peak output from the rectifier is set 170 volts dc from a a hundred and twenty volt ac enter.
The transfer assembly consists of the electricity enter socket and a push-button switch. The transfer is double pole, single throw (dpst), and is an exchange-action switch. Which means the switch controls two separate circuits and when circuit #1 is "on", circuit #2 is "off", and vice-versa. Moreover, the transfer has a place about mid-travel wherein both circuits are "off" to save you a quick-circuit via the bridge rectifier.
The mower's bridge rectifier is very smooth to replace. The recifier is hooked up inside the higher-center of the mower, just adjacent to the motor (see pics beneath). The rectifier has 4 connections, of which only 2 are commonly classified ( and ~ ). Per the wiring diagram shown above, there are 2 ac connections, marked with the aid of ~ , and a pair of dc connections, marked and - respectively.
Whilst the rectifier is changed, the two ac wires can pass on both ac (~ ) terminal. But, the dc wires on the and - terminals have to be connected with the correct polarity or the motor will spin backwards... And mower blades don't reduce very well spinning in opposite ;-).
Appropriate replacements encompass nearly any bridge rectifier with the same or higher scores. For example, diodes inc. P/n gbpc2504 and mb254 are 400 volt, 25 amp rectifiers that are suitable replacements for beneath $four. Those are available from digikey and lots of different companies. In fashionable, installing a rectifier with a higher-current score and/or increasing the size of the mounting plate should growth the life of the component because of reduced heating.
It seems that the authentic bridge rectifiers (black & decker p/n 72256-03) are rated 400 volts, 15 amps. Those factory components sell for over $10, which is type of ridiculous given that these are such common parts which can be available from almost any electronics supplier.
