| Need Help Wiring DC Motor with PWM |
| << < (2/7) > >> |
| PK:
Are you sure that terminals 87 only connect to the PWM output (ie not to the battery) You should be able to measure the DC volts across the motor change as you vary the PWM. |

I dont know to much about wiring but shouldn't the fuse go directly to the + pulse width control? The diagram shows it going to both the pw and the relay wouldn't that render the pw useless? |
| RobWilson:
Hi snub Just to clarify make sure the control side of the relays are wired up like so . |

A supply to the direction control In reality they would have their own fuse . But they would still be conecting to B+ |

The coil is connected to pins 85 and 86, pin 30 is the common connection for the contacts on pins 87 and 87a. Just wire up the relay contacts to give a double pole changeover arrangement. The fwd/rev switch then acts to either energise or de-energise the relays giving the fwd or rev action,is another way of doing it. |
