Fuse for heated suit

Woe unto you that bought the first model year of a major remake, perhaps this section can help address any 2014 and later model Ural "imperfections". Here's a special section for folks with the latest rigs to discuss 2014 and later model-related topics such fuel injection, 3-wheel disc brakes, hydraulic steering dampers, spin-on oil filters and other anomalies that don't belong on true Russsian motorcycle ;-P We've gone from using big hammers and greasy wrenches to needing computers and Ouija boards in order to fix our rigs.
Forum rules
Please keep this section specific to issues pertaining to 2014 and later models such as fuel injection, sidecar and rear disc brakes and so forth. Ask general or non-2014 and later specific questions in the main Hammerin' & Wrenchin' section.

Fuse for heated suit

Post by Kovar » Tue Jan 24, 2023 5:21 pm

RE: 2021 Gu
My battery tender has a 7.5 amp fuse. My suit uses the same connector. I used the battery tender connector and with the pants, jacket and gloves the fuse blew. The connector that came with the suit uses a 15 amp fuse. Any harm in using a 15 amp fuse in my battery tender or should I wire in the accessory connector that came with the suit?
Thanks

If it's a Battery Tender brand charging pigtail, they use 16 gauge wire in them, and it's not especially long. At least one wire size selection chart suggests that 16 gauge is good for 15 amps up to 3.8 feet long. Pretty sure that distance would be from the battery to the first load for the heated clothing. So you might be stretching it a little bit to fuse it to 15 amps, but if it were me... I'd try it. And I'd check once or twice to make sure the wire isn't getting hot, just in case. Beyond that, if one of your wires gets damaged and shorts, the 15 amp fuse will still blow, to protect you from setting the bike on fire.

Jacket, pants, glove liners, total draw ,11 amps. I put a 15 amp fuse in the battery tender SAE connector. Connector was warm but not hot. I think I'm good and my wiring is protected.

Sam,
Are you plugging your suit into the battery tender? :?

I think he's plugging it into the BT pigtail on the bike . . .

If you are repurposing the connector for the suit with a 15 amp fuse, put a 7.5 Amp fuse in line on the battery tender side of the connector to protect the battery tender and or the bike, when you plug it into the bike.

The inline fuse works either way protecting the battery tender from a fault on the bike and if or when the battery tender developes a fault.

And as Aduthie said, make sure your bike connecter and wire can handle 15 amps. An easy way to check is to see if your suit wiring is approximately the same size as the connector wiring.

When you say, "battery tender fuse", are you referring to the fuse that came with the BT and that's what you have hooked up?

If so, there is another SAE connector pre-installed in the 2019+ Urals. It is shown on the schematic as a cigarette connector but is actually an SAE. You can find it underneath the seat. It has its own on-line fuse, but I'm not sure of the amperage.

BT-Deltron and Gerbing years ago voided warrantee when they realized customers were using the same/similar connectors and pigtails for both products.
Add and use the supplied that comes from the manufacture product.
My heated gear uses 15 amp, the BT 7.5. They already did the math for you. But doesn't mean the wire/cable is proper for both.

The SAE connector came installed with the bike with a 7.5 amp fuse either from the factory or the dealer. I had the seat off to change the fuse. I was too lazy to to unscrew two fastener and hook up the fused coax connector that came with the suit. I'll go back and hook it up. Thanks all for the advice.
