elcamino/wheelhorse 9,358 #1 Posted September 10, 2016 I want to install an electric fuel pump , electric lift on the rear hitch and a winch on the front of a 1988 416-8 . I plan on using separate switches for each. Should I connect all to the red wire on the 25 amp battery line ? Not sure where to connect them . Also should I just cap the inlet and outlet for the existing fuel pump. tractor has a single cylinder Kohler motor. Next question none of the dash lights work . I know I need to check the connectors , but in checking the wiring diagram it indicates a rectangle object in the red wire coming from the switch on the battery ( wire number 5 on switch ) but does not identify the object. Thanks in advance for any help you all can provide. Share this post Link to post Share on other sites
Walt 339 #2 Posted September 10, 2016 Would need to look at wiring diagram but from your description I would guess rectangular item is a in line fuse. Share this post Link to post Share on other sites

pfrederi 18,084 #4 Posted September 10, 2016 The electric demystification manual doesn't show a 1988. They changed teth wiring a lot over its model life. Here are couple Could be the test switch. Share this post Link to post Share on other sites
elcamino/wheelhorse 9,358 #5 Posted September 10, 2016 @pfrederi Thanks for the diagrams , neither show what I am talking about , it maybe a quick disconnect @squonk Mike I have printed and read your thread on the electric pump hook up and still don't understand the relay and all the other stuff you discussed. Can I just hook into the power line ( battery ) that goes to the switch ? Or can I just connect to the battery ? All three electric units will have an on off switch. Turn key on , turn on fuel pump ,wait few second , turn key to start. Only use other 2 electric units when tractor is running. Share this post Link to post Share on other sites
pfrederi 18,084 #6 Posted September 10, 2016 i wire my electric pumps to the ACC terminal. The pumps are really low amp draw. Turn the switch to RUN for a few seconds that will fill the bowl then start her up the pump will start running again after you release the key from the START position. if you have a battery ignition suystem you can use the I terminal instead. I am old and having to remember a separate switch to turn on...and more importantly off taxes my few remaing brain cells. Share this post Link to post Share on other sites
elcamino/wheelhorse 9,358 #7 Posted September 10, 2016 Paul , I am old also , just typing this uses all brain cells that are left and I am not sure they all work 100 % of the time. Share this post Link to post Share on other sites
pfrederi 18,084 #8 Posted September 10, 2016 For your winch/lift i would run them right off the battery with appropriate gauge wire and fuses. Some winches draw a lot of amps. You may have to use relays if the amp draw is so large it will exceed the rating of your selected toggle switches. Share this post Link to post Share on other sites
elcamino/wheelhorse 9,358 #9 Posted September 10, 2016 @pfrederiThanks so much you have answered my questions in a few sentences. Can I just cap off the mechanical fuel pump. It is on a single cylinder 16 hp kohler. Share this post Link to post Share on other sites
pfrederi 18,084 #10 Posted September 10, 2016 (edited) Cap off the pump. This may be your wiring diagram looks like a fuse youcan down load teh dymstification guide from this site. Edited September 10, 2016 by pfrederi Share this post Link to post Share on other sites
squonk 41,750 #11 Posted September 10, 2016 Since I really don't like running anything extra through the whimpy key switch on a horse I used the relay. I'm a relay fanatic. Really simple. The key switch powers up a puny little coil that closes contacts that power the pump. You can see by this pick the fuel pump I used draws 5.9 Amps. That's enough for me to want the relay. The relay contacts are wired right to the Bat with a fuse and handle the pump current. Share this post Link to post Share on other sites
elcamino/wheelhorse 9,358 #12 Posted September 10, 2016 Thanks to both of you for your help. @pfrederi that is the diagram that I have been looking at. It maybe a fuse , I just need to dig around on the tower to figure it out , that (whatever it is ) may be the cause of the lights not working . The red wire goes from the rectangle to the number 11 spot on the light harness and then to the test light. This project is turning into more fun than a barrel of monkeys.
