Re: Help
NO..... but it looks pretty
What year is your cart and which drive system do you have? Then what seems to be the problem? |

Re: Help
Scotty, Ryan has a 96 TXT Series cart that has been modified.
The F/R switch was replaced with a pair of German made 3P-ST relays. Electrical specs unknown. There is another relay (Finder 55.32 series) whose function isn't clear and electrical specs are unknown. There is also an added terminal strip that a lot of circuits are routed through. If you go to his first thread posted, he has under seat pictures on pg-2. Ryan, your cart is unique, unless the person that modified it has modified others. If you can track down who the person is, he/she might be able to explain the exact hows and whys of it, but other than that you'll have to accept some generalizations. Except for the Direction selector switch assembly contained within the dotted lines, this is what you have, or pretty close to it. (Less accessory items) As you see, it is clear and concise, easy to follow and uncluttered. If you can draw what you have in a similar manner, how it works should become obvious to you if you have a basic understanding of electrical devices. If not, it can be explained in layman's terms. |

I saw the pictures from your reverse light posting in which it was proven your cart is unique. I think anyone who looks at your previous posts and these diagrams you have will come to one conclusive question.... WHY?????? What was the previous owner thinking? I'm sorry man. If I had your cart and diagrams long enough, with the proper amount of beer, I'm sure all the wires could be traced individually from point A to point B and some clearness could be found on what the heck is going on with your cart. JohnnieB's advise is as good or better than any I have seen in any forum. If you can answer his questions, albeit starting from scratch, you will most likely get some resolution. Until then, all I can give you is some sympathy. Best of luck Friend. |

Re: Help
FYI Gonkulor, this reversing contactor that Ryan has is a pretty common conversion to eliminate the F/R switch on a series cart. It's mostly used in high amperage conditions and also serves to utilize a rocker or toggle switch to change directions. It's more expensive than what Ezgo used in the stock cart but electrically speaking, is a much better way to do the job.

Re: Help
In my opinion and as dougmcp stated, using solenoids for direction control is better electrically than a high current mechanical switch, but as twp5253 stated, doing so gets complicated.
I don't know how familiar you are with how a series electrical motor works, so you may already know this, but I'll spell it out anyway. The Armature (moveable windings) and Stator (stationary windings) are connected in series, hence the name. The same current that passes through the armature passes through the stator. (This same current also passes through all the interconnecting cables on the batteries, all the high current cables to the speed controller, solenoid, F/R switch and to/from the motor.) The direction the motor rotates is reversed by reversing the direction current flows through the stator. That is all a mechanical F/R switch or solenoid type F/R control actually does, but high current is being switched, so some interlocks are added to keep the switching from occurring while high current is flowing. This switching of current flow direction through the stator can be accomplished with a high current double pole double throw switch, which can be actuated either by hand (IE: stock EZGO F/R switch) or by an electromagnet (aka - Relay/Solenoid/Contactor), but all of the solenoid F/R setups I've seen schematics of uses more than one solenoid. If the setup you've got is working, and the parts it is made from are readily available "down under", I'm not entirely sure I would change it back to stock since I suspect the previous owner used what was readily available in Australia rather than the solenoids typically used elsewhere. If it is not working, I would probably rebuildthe F/R switching device with different solenoids. Here is a basic diagram. This is electrically what you've got, except Controller and Throttle are different and your two F/R solenoids are depicted as two DPST units |

Re: Help
So, If I read this correctly....it has been awhile since I have done my setup. Your showing 4 SPST Solenoids to do the F/R operation? And, what would happen if one of them hung up during operation? Isn't that the benefit of the Albright SW202 or perhaps they could hang up too? Have you seen the Gigavac 600+amp solenoids? GX-16? Thanks, sorry for the hijak
