Installation
1. Theseinstructionsareforthefailureofonegatetooperatein
adualgateinstallation.
2. Identifythegatethatwillnotworkandcheckthecontrol
switchforthatgateandverifythatitisturned“ON”.
3. SwaptheGate1andGate2linearactuatorconnectorson
thecontrolboard.Ifproblemmovestoothergatethenthe
controlboardisbad.
4. Ifproblemremainsinthesamegatethentheproblemis
eitherawireproblemorlinearactuatorproblem.Sinceitisa
possiblewireproblemweneedtocheckthefollowing:
A.Wireharnessforcuts,nicksorbadsplicesifspliceexist.
B.Ifgatewithproblemisthegatelocatedontheotherside
ofdrivefromcontrolbox(Gate2)thecableunderthedrive
needstobeveriedgood.Thisisdonebyusingavoltmeter
andgoingtothejunctionboxlocatedbelowtheGate2linear
actuator.Locatetheredwirewithwhitestripeandtheblack
wirewithwhitestripeandthenoperatethegateandcheck
voltageonthesetwowires(expect12VDC).
C.Ifvoltageispresentwhengateshouldbeoperatingthen
theproblemismostlikelythelinearactuator.
D.Ifvoltageisnotpresentwhengateshouldbeoperating
thenmovebacktothecontrolboxsideandcheckvoltageon
sametwowireslocatedinthewirecompartment.
E.Ifvoltageispresentonthecontrolboxsideofdrivethen
thecableinthegroundmustbedamaged.
F.Ifvoltageisnotpresentinthecontrolboxthenwehave
missedsomethinginsteps2or3,recheck.
3. Gate 1 and Gate 2 will
not operate. Dual gate
installation
This assumes that the
inline 15 AMP fuse in the
Plug N Go Harness has
been checked.
1. Theseinstructionsareforthefailureofbothgatestooperate
inadualgateinstallation.
2. Verifythatcontrolswitches3and4areturned“ON”.
3. VerifytheredandblackwiresonthePlugNGoharnessare
connectedtothebatterycorrectly.Redconnectstopositive
andblackconnectstonegativepostonthebattery.
4. Verifythatthebatteryischarged,pressthe“Open/Close
Command”pushbutton,ifaclickingsoundisheardfromthe
controlboardthenmostlikelythebatteryisdead.Havethe
battery load tested to verify it is bad.
5. Ifbatterychecksgood(passedtheloadtest)thenthecontrol
boardismostlikelytheproblem.Tothinkthat2motorshave
gonebadwouldnotmakesensebutisalsoapossibility.
