Upgrading to a 24 volt motor -97' Lund


Hoovey

Question

I am replacing my 12V bow mount motor with a 24v model on a 97 Lund Pro V. I plan on running two 12V batteries in series for power, but I am curious if I can use the existing wire and plug adaptor for the 24 volt system? I'm not sure if I need different gauge wire and/or a different adaptor. Also, do I connect my on board charger to the batteries the same as I would connect the motor wires (red wire to positive of one battery and black to negative on the other battery)? Thanks.

DOES YOUR CURRENT PLUG ON THE BOW HAVE FOUR WIRES OR THREE. IF IT HAS FOUR (WHICH IT SHOULD)THEN YOU DO NOT NEED TO PUT THE BATTERIES IN SERIES BECAUSE THE TROLLING MOTOR PLUG WILL DO IT FOR YOU. WHEN YOU HOOK UP YOUR CHARGER YOU PUT ONE BANK TO ONE BATTERY AND THE OTHER BANK TO THE OTHER BATTERY. PLUS TO PLUS NEG TO NEG ON EACH. DO NOT PUT PLUS TO NEG. GOOD LUCK.

IF YOU ONLY HAVE TWO WIRES YOU ARE STILL OK. THE TWO BATTERIES WILL HAVE TO BE WIRED IN SERIES AT THE BATTERIES. RED WIRE FROM BATTERY ONE IS THE RED WIRE TO THE TROLLING MOTOR PLUG, BLACK WIRE FROM BATTERY TWO WILL GO TO THE TROLLING MOTOR PLUG, THE NEG FROM BATTERY ONE AND THE POS OF BATTERY TWO WILL NEED TO BE CONNECTED TOGETHER WITH A BATTERY JUMPER WHICH YOU CAN GET AT ANY AUTO PARTS STORE.YOU WILL THEN BE IN BUSINESS. GOOD LUCK

Sorry about the yelling but I am not good at typing. My kids are on ridlin for a reason. As far as switching from a motor guide and minkota motors the plug from the motor guide should be able to be used on the minkota. There are only a black and a red wire on each. if that does not look correct call me and i will get the answer for you. good luck jim 612-590-5833

You still do not have to hook them up in series. It depends on were your batteries are. If you want to stay away from buying a 2 bank system then you can run two more wires to the front (red and black) and install a four wire plug which only cost about $8.00. Every four prong plug has red charging plug made four them. the charging plug would go to the stayncharge harness and the plug for the trolling motor would automatically make it a 12 or 24 depending how you hook it up. the trolling motor plugs will have one black one red and one orange wire on it. the black is neg, the red is for 12 volt pos and the orange is 24 pos. This sounds like alot of work but it really is not. If you do it this way then you can use it with the stayncharge and you will be able to use it with a standard 12 volt charger. if i can help with this call me or give me a number and i will call you and give you all the help i can. good luck. jim 612-590-5833

Jim - great info here. Speaking for all the rookies on fm.com - "Thanks".

One additional Q for ya - I'm wiring my boat from scratch for a 24v trolling motor and I'm wondering which is better for power and battery life: in series or wiring each battery direct?

It really has nothing to do with battery life either way. If you are going to wire from scratch you need to run good wire and if you are not wanting to go out and buy a pricey on board charger then run two wires for each battery to the trolling plug because the trolling motor plug will put them in series for you and you will have more options on charging. every type of trolling motor plugs have a charging plug that can be installed on our products the stayncharge or you can even use the battery charger in your garage by putting a chargeing plug on the charger and use it through your trolling motor plug. remember good wire. good luck

      In addition to to Feichao, you can also consider the DJI Mini SE. This is also an excellent piece. However, always try to read articles and thorough reviews before buying.

      Mini drones like Feichao Mini Drone Quadcopter M9 are good to take footage.

      My grandmother is a very old person, and she has had a real estate company for 20 years now, she has dedicated her whole life to it, so she does not understand much about technology and is looking to modernize her business, she is one of the few real estate companies that They don't have their own application, so I see myself in charge of finding a good software developer for real estate and that type of business. Do you know any professional or company that is dedicated to it?

      Don't forget about IP Lures just west of town about 2 miles on the south side of Co. 82.    I was out on Osakis last week for a couple hours. Picked up two walleyes, one about 13" and the other a fat 14-1/2". Also a couple northerns and a handful of perch.

      Of course, you shouldn’t even ask about this, because this is the responsibility of the executor of the order, that is, the employee who will create such an application. I think it will be stated in the contract of employment if there is one and then you don't have to ask for anything.

      Shallow. Got skunked tonight. Just got chased off by the weather. Last evening was the only time the last 4 times out I caught fish. Last even was light drizzle and calm water. Water warmed up about 3-1/2 degrees since the first time out.

      It is very important not only to identify mushrooms by their appearance but also to understand whether it is useful or not, because now there are many poisonous mushrooms, and it is extremely important that no mistakes were made in the selection of such mushrooms. That's why I here https://www.mushrooms.online/mushroom-poisoning/ read a lot of interesting information about poisonous mushrooms and was able to understand more about it. I hope that I was able to help you and was really helpful to learn.
