How To Test A Battery Solenoid
Вставка
- Опубліковано 1 вер 2021
- In this video, we test an RV (1999 Ford Econoline) where the house battery isn't charging. Learn to test a battery isolator solenoid using DYVO. Understand the limitations of traditional battery solenoids and why it is better to use an automatic charging relay or latching solenoid (switch) such as the Blue Sea Systems m-ACR 7601. Also applicable to starter solenoids and continuous duty solenoids.

Great upload, thanks. When i hook my isolator solenoid up it seems to fry my starter solenoid. Have you seen this before? Will replacing the isolator solenoid fix this?
Unless it's a pan on a stovetop, frying is never good. With electrical, "fry" is a generic term that can mean a lot of things, so we're not exactly sure what you are seeing. We don't recommend replacing parts unless you've tested them and verified they are faulty. The isolator could be defective, but it might not be wired correctly. The battery isolator is only meant to combine or disconnect the starting battery and the house battery. We have a schematic on our website that shows a general overview of how these components are connected. dyvo.us/how-to-guides/ **Note: the schematic is for reference purposes only. No circuit protection is shown in the schematic. Best of luck!
Can you do a video of starting system voltage drop testing with dyvo??
Absolutely! We've got a lot of new videos we'll be releasing over the summer. We'll make sure and include starting system testing and voltage drops using DYVO. Thanks for the message!
Hello. Is it best to remove/disconnect battery when replacing selonoid as to avoid shock? Or...is this not an issue? Thanks.
Great question! We recommend disconnecting the negative battery terminal when replacing/installing any component where shorting can occur. Battery isolators and starter solenoids have open contacts that are always "hot". This means, you could accidentally short the contacts when servicing them. Headlight bulbs are an example of a component that typically does not have open contacts, and the circuit can also be turned off, therefore, disconnecting the battery before servicing is usually not needed. The purpose of disconnecting the negative battery terminal is to prevent accidentally shorting a positive and ground. You do not need to remove the battery unless it is in the way of the component you are trying to access.
@@dyvoautomotive Thank you! My 2006 Dodge Sprinter View RV is having house battery issues. Replaced them...but there is no power coming from them. I will try and replace the solenoid next and see what happens. Thanks.
@@jimmoses6617 We recommend testing the solenoid first before replacing it. If it doesn't have the signals it needs to operate, installing a new one won't fix it. Best of luck!
Wow! Thanks, my suspicion is confirmed. I have a 2023 Winnebago Solis Pocket exact situation, the house doesn’t charge while driving but the chassis does. I have been searching and also inquired to Winnebago to locate the solenoid on the rig to replace. If you know, please share!? Thanks for the video!
… also, are both house and chassis connected to the solenoid?🤔 if the chassis batt was charging but not the house batts?
Thanks for the comment! Unfortunately we don't know the location of the battery isolator on that exact vehicle since Winnebago doesn't publish their design specs. Hopefully Winnebago can tell you? If it is a solenoid type, you can try to listen for a "click" sound when performing key-on, but that's only if it's working and still might be tough to locate. It could be next to the engine battery or house battery.
@@StoneRunning23 Yes, both house and chassis batteries are connected to the battery solenoid/isolator. The purpose of this isolator is to connect or isolate the engine and house batteries from each other, so they both must connect to the isolator. Smart isolators, such as the one installed in the video, are capable of "looking" at the voltage of both batteries. If one falls below a certain amount, it opens and isolates the batteries. When the voltage of either battery goes above a preset amount, it combines the batteries. To answer your question, if the chassis battery was charging, the isolator will combine the batteries to also allow the house battery to charge, and vice versa.
Sir upload new video
Thanks for the comment. We'll be adding a lot of new videos soon!
