Expand picture to see how to connect wires. Really easy just follow the wires. When all connected flip switch on which only works one way. Don't use glow plug yet. Flip switch on, you should see your battery voltage. Push left button which will show output voltage. Turn the small brass screw connector clockwise to lower output down to 1.4 or 1.3, when set test glow plug. Push right button to turn on or off for plug. I just leave it on because the main switch turns it all off to keep battery from draining. You have to maintain more than 4 volts for board to work, & plug will stay lit for 20 seconds & will shut down. Could be a safety for over heating.
All you need to do is decide what switch you want to use & build your box however you want to set things up. I haven't tried using just a normal 9 volt battery yet, concerned about mah. Not sure how to post a link yet but will look into that. Later on I will go to lows & get micro male & female plugs so I won't have to de solder wires from switch. I have used this for a year With no problems & I don't think it will take you 20 seconds to start your boat. Buy 2 boards in case one burns out. 12.99 a piece at amozon. If you want link faster email me at
[email protected] & put glow plug board in subject line, I will send link.
This is my contribution to the hobby. & the more parts you have the cheaper. I used Dubro glow clip & used a micro switch I think from amozon. Let me know what you think good or bad there's always a better way. Wood 1/16 with 1/8 plexiglass lid.
It's a drok board 2 3/8 long
1 3/8 wide 5/8 high. Not all boards are same this is a micro buck converter. Look for the positive & negative stamped on board so you can't mess up.
