IS it dangerous to plug the handwarmer in parallel?

Hi! (sorry for my bad english)

mY handwarmer don't warm enough and i tried it plugged in parallel and it works.

Can i damage something ?? stator or cdi etc etc??


I tried to find the trouble but couldnt find anything wrong. (did check the cable under the engine, all the electrical wires, cdi box, stator, variable resistor etc etc )

ITs an srx 2001

For now, the thumb would work intermittent,, and come hot,, but not the handwarmer.. I already checked in the past, Voltage and amp that goes to the handwarmer and everything was in the spec.. I just dont understand . When i plug them in parallel, of course, it warm better...

I'm very sick now to have my hand COLD with the -30C we got here these days when trail riding
 
load current goes up by a factor of 4... stator now needs to generate that current and CDI must allow this current to flow through it... I'd be careful, it's a simple solution to a problem but electrical/ electronics might not be designed for such high current... my .02... tj..

damn :( we need to know how many amps the CDI could draw without blowing

On my 98 SRX the thumb warmer is HOT compared to the hand grips. I have to turn it on about half to be comfortable for the thumb and then the grips are questionable. Is this normal or something wrong? :dunno:
 
hey fortress j'ai changer toute mon system pour mettre celui du 2001 pis chu arranger comme toi lollllll .....je crois que ma les installer en parralle aussi car si je mais juste une poigner ca marche parfaitement .....on dirais que 12 volts dc ces pas assez pour les handgrip en serie ......

Salut!! Mais pourquois les poignées fonctionnais a l'achat du srx neuf et plus maintenant?? malgré de nouvelles poignées etc etc.. J'ai tout vérifier au multimetres et tous les chiffres semble dans les specs mais pas de chaleur,, J'y comprend rien....

Sauf que la, nos amis ici nous disent qu'On peut sauter le cdi... en parallele
 
Not many of us speak French . . .

I would get an ohmmeter out and test each warmer by itself. Then hook it all back up except the power lead (yellow-red) and test the disconnected grip lead (side that goes to the grip) to ground (chassis). If you were not able to produce heat then you likely have extra resistance somewhere in the circuit or a bad ground.

Your grips should be .8 - 1.9 ohms each depending on which ones you have.
Both grips to ground should be 1.6 - 3.8 ohms (in series).

Then test your warmer control dial variable resistors. They should be 400 - 600 ohms.

If you are out of range on any of these, replace the part. You may want to verify my numbers in the manual for your specific model.

You could run in parallel and possibly be fine, but this is simply a band-aid. My guess is that this is an intermittent problem, so you do run the risk of overloading the circuit in the CDI but it is somewhat unlikely.

I calculate the current to simply double. Say from .5 - 1.3 Amps for in series up to 1 - 2.6 Amps in parallel. If you have about 20 Volts at 3000 rpm this would be 20 - 52 Watts of power consumption instead of 10 - 26 Watts.

Post your numbers from your testing. Also just curious how you tested for amperage.

I would not run them in parallel at all. You are pushing approx 3 times the current thru the circuit, that it was designed for, somthing bad is bound to happen!

I believe that this model (2001 SRX) already has the thumb warmer on a separate circuit from the hand grips. Am I losing my sanity, or is this really simply doubling the current (cutting the resistance in half)? You are the second one to suggest more current than double. Am I mixed up some how?
 
got same problem here ... everthing was perfect on ac circuit with my 98 then i switch to 2001 electric system srx with all stuff .. switch handwarmer for new one and found out no heat at all ...i got the same issue he got...if u plug only one hands if work perfect and way to hot ..u plug both so u add resistance in circuit and no more heat ....got 12 volts at yellow red wire only way i think it could heat more that way it to raised voltage ...yes thumb and hardwarmer are not together... resistance is to high somewhere or the voltage is not high enough not sure yet

Test Test Test - It should show you the issue. While the symptoms are similar, you likely have different root causes.
 
maybe but we have similar issue lollll...same voltage and still no heat but i will find out..
 
i think it will result i will plug them in parallele and never put them at maximum ...if i don;t put them at maximum it will not take more current that normal way at full blast...and they will heat so so mutch lolll... if cdi fail i will call a towing

well. in an old post from me, i already posted the number i had and they were the same as everyone.. Its just bizarre.... but it was a 5000 rpm,,, i should let my ohmeter plugged while i'm riding faster and see what happen

well, if the handwarmer are 4ohm and you put them in parallel, at 12 volts, you will drain 6 AMP instead of 1.5 amp in serie
 
when you place them in parrallel, the effective resistance (RT) is one half the value of one single grip resistance... 1/RT=1/R1+1/R2

for series, RT=R1+R2....

You're resistance is double in series but 0.5 in parallel.... factor of 4..... too much load current for my pocket book:)
