Battery tray solenoid replacement - is this best option?

Hi all,

Is this the correct part to replace the solenoid on the back of the battery tray on a 1991 250 Classic?
many thanks
Nick
Sure Power Battery Separator
Part #: 1315-200

The Sure Power Battery Separator is designed for use in multi-battery applications as a excessive loading while allowing auxiliary batteries to be charged. The Sure Power Battery Separator has two basic operational characteristics.

Might be a bit overkill. You might consider this one. Cole Hersee: 12 Volt Insulated Solenoid with Silver Contacts - (Part#: 24143)

If price is an issue (it always is for me), this one is cheaper although it has mixed reviews:

Amazon.com: Customer Reviews: Tekonsha 7000 12 Volt 3 Terminal Battery Isolator

The thing I don't like is they give you no specs. The Cole Hersee is continuous duty and also rated at 200 amps. They do have a 80 amp continuous duty unit for $23 but you are linking the 2 house batteries to the start battery so 80 amp might be a little underrated. Also probably don't need a continuous duty for starting but that doesn't seem to be an issue price wise.

I would hope that the starting battery should start the engine by itself but Airstream seemed to think there was a need for the back up so they installed the solenoid. Good luck.

Thanks - I like the look of the cole hersee over the other brands, including the Intellitec. I noticed Cole Hersee have actually released an updated version which has some other advantages (see below). I'm trying to find a supplier

http://www.colehersee.com/home/item/cat/168/24213-01/

The silver-tungsten contacts provide the best available conductivity and are more weld-resistant than standard silver contacts, company officials said, adding that the design minimizes arcing and contact oxidation, therefore always maintaining high performance. The solenoids are designed for universal use for loads up to 200 amps. Several environmentally-sealed options are available, including encapsulated solenoids 24213-01 which withstand moisture and dust to IP66 standards. Where vehicle vibration may be a problem, model 24213-01 features potted internal windings for added protection of coil leads and studs.

Are you talking about the solenoids that disconnect your coach and or chassie systems? If so look up Intellitec on the web. The store and operate switch is inside the entrance door and the solenoid(s) are attached to the back of the battery tray.

Hi all,

Just to clarify, I'm trying to replace the Cole Hersee solenoid with aux starter which is attached to the rear of the battery tray on my 250 MH.

The surepower 2303 is the blue finned isolator is inside the engine bay which is fine.

I had hoped to replace the Cole Hersee battery tray solenoid/aux starter with the following product:

Sure Power Battery Separator - (1315-200) ~ All Battery Sales and Service

My understanding is that the Sure Power: 12V 200A Battery Separator - Bi-Directional w/ Aux Start will replace the faulty Cole Hersee battery tray solenoid, still give me the aux start function and offer the added benefit of charging my chassis battery when on plugged in power (or Solar) in the future.

Would someone be so kind as to confirm that I have understood this correctly?

many thanks
Nick
