Actually the IG2 signal is good for almost 99% of the time, unless you keep ON position for a looong time AND your AUX battery just happened to be very drained. I basically agree every sentence you wrote. However, this can be easily mimic by activating the solenoid with an ignition wire such Titanpat57ĭid in his write up I rarely see our battery voltage drop below 13 volts when the engine is running so IMO, it's close enough I mean who really sits there with the key in the on position and the engine not running for a loooooong time right? It really is just a voltage sensitive controller that opens or closes the solenoid based on the voltage (along with a nifty way to monitor each battery voltage when they are isolated and a forced 'link' feature). One thing I am not sure about is how long this signal persists.I forget if its only for when the remote start is in use, or if it's always active you'd need to manually test that out, sorry!įrom what I understand about the IBS, it basically only connects the two batteries when the ignition is on and it detected voltage is above ~13 volts or so and disconnects them when it drops. This should provide you a ground signal while the engine is spinning. That's great to hear you actually have an aftermarket remote start.if you do happen to want to go this route look up the model number of the remote start module, and then try to pull up the wiring diagrams to find the 'GWR (ground when running)' output it's also sometimes called the 'status' output. Hope that helps? I don't know anything that's hot when the engine is physically running only.

If that works you can use this circuit (driver's footwell fusebox) and access it with a minitap if you want: The key has to be in the 'run' position, or the 'acc' position to be hot. I think you will be fine with an 'ignition-on' signal. Sorry man- I've been slacking on the PM's as of late! Got to catch up. I know Voltage Sensitive Relay can make a such signal for you, I just wanna know if I can get a such signal in a very simple way. Don't get me wrong, I don't object to some dual battery systems like IBS, they are decent systems. No offence to the gentlemen I PMed for this question, I just couldn't wait for your reply. Can anyone tell where is the 'hot' signal only when engine is running? I found the IG2 signal in 'K Unit' in fuse box, but it's not the correct one. Joe Heitker, Senior Director of Strategic Sales, KOST USA, Inc.I'm thinking of setting up my dual battery system, and trying to find a Engine/Alternator running signal in fuse box(or wherever) to control a solenoid.

Emily Featherston, Product Application Supervisor, POLARIS Laboratories.Different types of coolants and what is best for your fleet.Want to learn more about coolants? Attend this webinar to learn about: If the cooling system becomes damaged, you risk the possibility of the engine overheating causing downtime for your business. Not monitoring the coolant could result in corrosion and/or sludge, which can impact proper function of the cooling system. Coolant can break down and become less effective over time. Did you know coolant is just as important as your engine oil when it comes to your fleet? Coolant needs to be monitored and tested because mechanical and/or chemical reactions can take place hindering the performance of the coolant.
