INTRODUCTION CraneHI-6Spartnumber6000-6300isforgeneralpurposeapplicationsandincludesauniversaladapterharness.Partnumber 6000-6301 includes a plug-in adapter harness forFordTFI-IVapplications.Partnumber6000-6302includesaplug-inadapterharnessforlatemodelGMapplicationswithdualplugcoil.

The Crane HI-6S is amulti-spark inductive ignition spe-cially optimized for street driven performance vehicleswithanengine redlinebelow8,000RPM.ARISCmicro-controllermanagesallfunctionsoftheHI-6Sincludingthestagerev limiterandtimingretard functions. If rev limiterortimingretardfunctionsarenotrequired,theHI-6Salsohasananti-theftfunctionthatusesaswitchhiddenunderthedashtoselectaverylowrevlimittokeeptheenginefromstarting.

WhiletheHI-6Shasarangeofbuilt-inretardfunctionsinclud-ingboostproportionalretardusinganoptionalboostsensor(P/N 9000-0110), use of these built-in retard features pre-cludesuseofthebuilt-inrevlimiter.Ifanapplicationrequiresbothrevlimitingandretard,youwillrequiretheoptionalTRC-2TimingRetardControl(P/N6000-6425).Refertopage9.

INTELLIGENT MULTI-SPARK Multi-sparkisgeneratedbyrepeatedlyturningthecoilcurrentonandoffduring thesparksequence.At lowRPM,duringcranking,theHI-6Sgeneratesupto12sparks.Thisassuresquick starting even under themost adverse conditions.Atidle and cruise, the number of sparks fired is adjusted tomaintainatotalsparkdurationofabout20degrees(crank-shaft),assuringsmoothidle,improvedthrottleresponse,andeliminatingtheleansurgecharacteristicofsomelatemodelemission controlled vehicles.

IdentifyCoil-andCoil+.Ifyouareunsure,refertoyourvehiclewiringdiagramorusethefollowingprocedure.LabelandthendisconnectOEwiresfromthecoil.Turntheignitionswitchon.Usea12volttestlightorvoltmeter.Thewirefromthe ignitionswitchtoCoil+will be hot.Cut thewires several inches from the coil andconnecttotheHI-6Sadapterharnessasshown.IfmorethanoneOEwiregoestoagivencoilterminal,cutbothwiresandconnectthemtotheHI-6Sadapterharness.AllOEwiringtothe coilmust be interrupted and routed through theHI-6Sadapterharness.

Ballast resistance. Somevehicles(suchasearlyChryslerwith4or5pinelectronicignitionmodules)useballastresis-tance.Thiscanbeintheformofaballastresistororresis-tancewire between the ignition switch andCoil+ terminal.ForproperoperationoftheHI-6S,ballastresistancemustbebypassed.Locatetheballastresistororresistancewire(refertoyourvehicleservicemanual).Bypassitwithheavy14or
