Jumpstarting a quad

[d33pt]

I jumpstarted my quad the other day with my car since the battery was dead. Is this bad? I read in the manual that it could hurt the electronics, but it didn't specify what. Didn't seem to cause any issues. What do you guys think?

[fasterthanyouex]

you could always roll start it? if you find a hill or if you are quick enough

[nosliw]

it's fine. never had any problems doing it.

Yeah it's fine just don't charge your battery w/ a car battery charger. it chargers w/ to many amps than needed

[m1ke]

isnt 2 amp charge ok?

[d33pt]

I hope 2 amp is ok...my charger says the 2amp setting is for motorcycles..

[m1ke]

I used 2 amp on mine, works great.

Jump starting a motorcycle/Quad can damage the Voltage Regulator/Rectifier. It's the square finned piece mounted behind the battery. The regulator rectifier is responsible for the converting ac current from the stator into dc current used to charge your battery and power your lights, etc. The Regulato/Rectifier also limits or Regulates the amount of voltage charging your battery; after a certain point the voltage created by the stator will be diverted to ground, so as not to over charge your battery. If you damage the Rectifier/Regulator you will start killing batteries. If you want to test it, connect a voltmeter across the battery terminals while the bike is at idle. Then gradually increase the RPM's: the votage reading should steadily increase to about 15.5 volts after that it should be diverted to ground. If you get a reading above 15.5 you are over charging your battery and the rectifier Regulator should be replaced.

i suspect that a damaged rectifier has more to do with banging away on the starter because your "havin issues"..
in that set of events, one would go as far as to "jump-start" the quad, due to the thrashing the battery has been through..

the starter only draws what it needs.. you could use an 8-D (semi-battery) or a 100amp battery charger and its not gonna ask for any more amperes than before.

the transients from the starters solenoid will eventually damage the semi-conductors of the "rectifier", but just adding an additional 12v DC supply to the existing 12v DC supply would only give you more energy to keep cranking away.
