1998 SCRAMBLER ?
#1
Has anyone disconnected the speed limiter system on this quad? Does it give the quad more power,does it damage anything? In the manual it says it can be disconnected just for testing puposes.

Thats kinda what i,m wondering is it the same thing?
ELECTRICAL
Speed Limiter System
Speed Limiter System Testing
CAUTION: Pre-1998 Models (except 1997 Scrambler 500) The speed limiter control module may be permanently damaged if the machine is operated with the voltage regulator damaged and/or the battery disconnected. WARNING: The speed limiter is a safety feature and should never be disabled, except for testing purposes. Serious injury or death may result if the limiter system is disabled.
When problems occur that sound like a spark-related "miss", the speed limiter system may be at fault. To determine if the limit system is causing the problem, the system can be temporarily disabled.
Disconnect' the black wire from the 'COI module':, The limiter system will then be disabled. If the problem still exists, the limit system is not the cause. If the problem goes away, re-connect the black wire and proceed with limiter system tests on the following pages. Verify all wires are clean and tight.
Module Wire Color Function
NOTE: Refer to the model specific wiring diagram for wire colors. Modules may not have all wires indicated below. Black wire - provides ignition control to the CDI module
Green or Gray/Orange wire - receives reverse gear indicator light signal from purple wire through override button White wire - receives a voltage signal from the ETC switch
Yellow/Red wire - receives the engine speed/ RPM signal from alternator
SYMPTOM CAUSE CURE
Limits in forward High Limit
(Reverse Limit) -Voltage to Green or Gray/Orange
wire in forward gear
-Voltage to white wire. Most often
caused by moisture in ETC switch.
-Inadequate throttle cable tension. -Check circuit to determine reason for voltage to
green in forward gear
-Clean, dry, repair or replace the ETC switch
assembly as required, inspect/adjust throttle
cable/ETC switch, or determine reason for voltage,
on white wire
Low Limit
(ETC Limit)
Engine miss at idle or rough
idle -ETC switch adjusted incorrectly
-Idle speed adjusted incorrectly -Adjust ETC switch until switch plunger is comple
depressed. No plunger Clearance. 1/16-1/8"th bill
lever free play. (Readjust Idle) _ $<
Backfire on deceleration
(disappears when black wire
is disconnected from speed
limiter) -ETC switch adjusted incorrectly
-Faulty ETC switch -Adjust ETC switch until switch plunger is coal! t-s(ii
depressed. No plunger Clearance.1/16-1/8" .1lroiiii
lever free play. (Readjust Idle)
-Dry out switch with electrical contact clean
replace switch, or adjust throttle cable free?
No limit in reverse -12V not present on Green or
Gray/Orange speed limiter
module wire
-Black wire from limiter module not
connected to CDI module black
-Yellow/Red wire on limiter module
not receiving an RPM signal
-Override switch not closing
-Faulty or incorrect limiter module -Check and repair reverse light circuit or ertr
selector switch. NOTE: if reverse light f
properly, the gear selector sw it c h is p ot . i t r
-Repair black wire between limiter a,h,d
-Check wiring and alternator output. r:?
-Test override switch function
-Replace moduleg
Limits at wrong RPM -Improperly charged battery
-Incorrect limiter module for
machine application
-Incorrect alternator output
-Faulty limiter module -Charge or replace battery
-Check parts manual applicatiO
-Check wiring and alternator
-Replace limiter module . ,,

YES, PLEASE. Copy and paste this manual from whatever it is in into a Word document! Send me a link or an email, PLEASE.
