what exactly can go wrong in a SWITCHBOX?

[indicafilms666]

it seems to me that the switchbox is just a terminal post, but what do i know. heres one for ya:<br /><br />from what i can gather, it seems that there may be a capacitor in most switchboxes hidden inside. ok that can fail however....<br /><br />on my 95 115, they used a new stator and it comes with a back box called a cdm module. from what i can understand, that box contains the electronics that the older switchboxes used to contain. am i wrong on this?<br />therefore, if my theory is correct then my switchbox is really just a terminal post and there is no electronics inside so if i have electrical issues i should be spending more time checking the stator/cdm assembly and not worrying about the switchbox, barring poor connections<br />anybody familiar with this type of setup?

Hi Indica,<br /><br />If you have CDMs you don't have a switchbox. The CDMs replaced the switchbox. Each CDM is the rectifier, Capacitor and switch for that capacitor, it also contains the 'kill' circuitry for the system.<br /><br />Now, if you post your serial number I'll know if you have a switchbox or 4 CDMs.<br /><br />Chris..........

Re: what exactly can go wrong in a SWITCHBOX?

ahhhh thanks chris thats all i needed to hear.<br /><br />ok then, what is the box mounted on top of the motor which has electronics encased in gel with 6 wires called then?

What colours are the wires? <br /><br />Chris............

Voltage Regulator

I suspect that too, but I'd like to be sure before offering advise.

thanks again chris<br /><br />i have to go check to make sure but i AM sure that :<br /><br />there is a black long cdm box, about the size of 2 cigars. on one end there are 3 wires, on the other end there are 2 wires. one end has a black wire going to ground and a blue and a blue/white. on the other side there are 2 wires im not sure what color.<br /><br />is this enough info?<br /><br />so that thing on top is the regulator? it has 3 pairs (6 total) of wires. one pair is yellow<br /><br />so what do you think? do you think my voltage regulato took a crap too or is it just my stator/cdm<br />thanks again

Re: what exactly can go wrong in a SWITCHBOX?

ok, I'm lost. CDMs are not long and thin. They are square-ish and have a multi-pin connector on one side and a spark plug lead coming out the other. You should have one for each cylinder. <br /><br />

so that thing on top is the regulator? it has 3 pairs (6 total) of wires. one pair is yellow

Probably. <br /><br />Not sure what the problem we are trying to fix here is either. <br /><br />Chris...........

Do you have a service manual? Thought not. GET YOURSELF ONE!!! In the meantime this is the wiring diagram. Does this help you any?<br /><br />Oh, and the manual, you have 3 choices.<br />Genuine,<br />Genuine and,<br />you guessed it, Genuine.

Re: what exactly can go wrong in a SWITCHBOX?

thanbks again chris<br /><br />no thats not it, but it helps. its must be a different setup. the 4 thingies with spark plug wires are my coils, they r cheap like 26 bucks a piece. what this fails to show is the stators companion which is a black box which i already located w pics online. it cost 224 and it comes with the stator. its called a red stator w cdm box. i think they only used it for 2 years.<br /><br />either way a boat junkyard has one in mint condition, guaranteed to work for 130, im popping it on tommorrow and maybe ill have spark and a running motor<br /><br />so what about the voltage regulator then? what happens when she fails? can she cause a no spark in all cylinders condition?

Usually not.<br /><br />ok, How about this one?<br /><br />

Re: what exactly can go wrong in a SWITCHBOX?

Achris<br /> I think he has the red stator kit installed with the voltage regulator adapter. it was common in 95. when the black stator failed, and all did, the red stator kit came with an adapeter to adapt the voltage output to the original switchbox. the red stator kit later came with a new battery charging voltage regulator as well. last kit I bought was about 560 dollars. if the battery charging regulator fails it will have no effect on ign. you may end with a dead battery but will still have spark when ya spin the flywheel. the no spark can be a failure in the kill circuit, can be tested by dissconecting the blk/yellow wire at the switchbox. can be a failed stator , can be a failed ign adapter, can be a failed switchbox. will require the service manual with the tech bulletin on testing the adapter as well as a peak reading voltmeter to properly test the system.

It's all coming back to me. Red stator, adapter, ugh!
