Scanner resets when cranking vehicle...
- Thread starter RRR
- Start date
If you connect a battery like that with out using an isolator you are running the risk of problems

just go buy the SDS100.

thanks RRR for enjoying that.
a friend years ago had some 12Vradios that he said he could listen to while driving.
i said so can i, and i can listen the whole time.
during one of the hurricane things, they closed part of rt75 and he missed that and got caught in the middle of it.
i heard the whole thing, but did not leave anyway.
i had five kids and always had plenty (dozens) of AA batteries around, so even if the power went out, i had weeks of time.

I have one already, and I thought you were being sarcastic...
I am merely wanting to resolve the issue with the '200 rebooting when I crank the vehicle, as dependable and simple as possible, without creating another issue. I have the '200 permanently mounted, with a drilled roof mount Laird multiband antenna. It performs well, and it's there to stay.
I will bring the '100 along if I am going to stay somewhere overnight. (It has the internal GPS, etc. etc. glad I jumped on that offering when I did)
Love the SDS series for sniffing stuff out.
I also have a '996P2 mounted in there also, that is the workhorse for normal scanning. I run it off the same type of Laird multiband, on the other side of the roof. I have had great experience with those antennas. Definitely spend the money for the springbase.

years ago it was voltage pulldown as the starter took a lot of juice.
today some circuits get turned off while cranking.
do you have it wired direct to the battery ?

If it were so then a million tow behind trailers would have blown up. But they don't. As added insurance an ignition triggered relay to disconnect the secondary battery from the first could be added. The example is only one cheap solution. They work. Others do provide isolation and automatic disconnect.
I have seen over my 40 years as a Firefighter and Electronics Training putting a 7 amp battery on a car is asking for trouble.
The isolator allows the battery to stay charged and keep the devices connected to it operating but not feed back to the reset of the car.
By the way what professional training do you have?
What is the purpose of a battery isolator?
A battery isolator prevents a secondary battery from draining a primary battery. It also allows an alternator to charge multiple batteries.

How it works
- A battery isolator is usually placed between a starter battery and a secondary battery.
- When the engine is running, the isolator allows current to flow from the alternator to both batteries.
- When the engine is off, the isolator separates the batteries so the secondary battery can keep its charge.
- Battery isolators are often used in recreational vehicles, boats, airplanes, and large trucks.
- They're also used in vehicles with high-power car stereos and off-road vehicles.
- Battery isolators help ensure the starting battery has enough power to start the engine.
- They protect the primary battery from being drained by the secondary battery.
- They allow an alternator to charge multiple batteries.

Fire-MAN. Did you actually read the product description and how they operate? Did you review your "How it works" section and then go back to the product brief?
Ummm. Are you asking for my educational background, resume', and references? 17+ years Technical Services Manager for a mission critical company on Florida's Space Coast? How's that work?
Sorry if my skills don't expand to chicken bar-b-que's and collecting loose change into a boot at busy intersections. Kudos if yours do.
Look. Up in the air, saving a kat. Faster than an agent with warrant bashing a door in. Capable of dousing a Tesla with a hose. Its Fire-Man!!
Yeah, okay. The dude asked for a solution to keep his radio running when he changes from accy. to on, and hitting start.
Not so sure import-car-meet-super-capacitors paralleled to the main main battery without any isolation is the hot ticket.
But there sure are a lot of tow behind trailers and such with a safety brake cable there to apply current to the electromagnetic brakes if an unscheduled rapid decoupling should occur.
And the battery in those battery boxes aren't that big. AND....they have considerably less ampere hour capacity than the starter battery in the vehicle it was attached to. With NO charge controller. And usually no battery disconnect, isolation device. Never saw a Fire-MAN responding to those. Could I get a couple breasts and drumsticks, and macaroni salad with that?
I had this problem with my BC210 and the solution was a pack of D cells in a holder with a diode from both batteries to the scanner so they would not back feed each other. The batteries lasted for years as they only had to power the radio for a few seconds.
Yes and I have seen the smaller battery short out during a large draw like starting most nice trailers have built in isolator just like the one in you very on post. I have seen fools add the small battery in parallel no isolation ended up having a small fire. Like I said using the small battery with ni isolation is not wise. You posted the correct thing I just added to make sure for others to us isolation and you misunderstood it was not an attack towards you.

Why not just wire directly to the battery in the car? Granted, if you forget to turn off your scanner the battery will more than likely be dead.
