Moroso super duty battery disconnect switches, with a rating of 2,000 amps intermittent and 300 amps continuous, are perfect for engines with a large starter draw, RVs, drag cars with alternators, and other applications. Two pairs of copper studs make these switches ideal for disconnecting alternators or other electrical devices in addition to the battery. They feature sealed shafts, which keep out moisture and debris, and the indexing pins align the switches with the mounting panels to prevent rotation. These super duty battery disconnecting switches include switch position face plates and decals to indicate switch location during emergencies. They are for use with Moroso push/pull switches for remote installations.

Questions & Answers Ask a Product Question
Q:

Hi, My name is Tim. My truck still runs when I cut the switch off. I have it weird per the instructions. I even switched the alt wire and jumper wire around.
I do have the exciter wire for the alt. hooked to my switch for the MSD box.Would this cause my truck to still run? Any body else having problems with this switch? Am I missing something?
TIA
Tim

Asked by TIMOTHY E on March 25, 2018

A:

any source of power to the field terminal on the alternator will make it produce voltage, hence keep it running. don't know exactly how you have it wired but try eliminating that source and see what happens. the moroso i got (that i'm sending back) alternator contacts were only rated for 20 amps. i have NEVER seen a alt. rated 20 amp output. you might have fried the contacts. (welded them together) i ended up ordering a battery switch wit a 125 amp alt. rating

If you have a car with a relocated battery that you want to race, you need a switch. if that car runs an alternator you want this switch. Very heavy duty large terminals. I'm glad I chose this one.

Great product, hard to find parts.

My only complaint was trying to find terminals for this switch. You will need a ring terminal that can accept a 1/2" stud. I had to modify a 3/8" terminal to make up setup work. This switch is a well built sturdy piece of hardware. I used an Ohm meter and checked all the functions of the switch, everything worked without issue. Great product overall. ...read more

Not the correct part for high amp alternators

Summit RacingSummit Racing Verified Purchase

MOR-74102
This is a well built, beefy unit with 1/2" battery terminals. It includes alternator disconnect terminals. HOWEVER...The alternator terminals are only rated for low amp alternators 20 amps max. I ordered the wrong part here. My fault After consulting with Moros tech...The correct part # for my application was 74108 - This unit is rated to 125mp for alternators. I added push/pull kit # 74105. I ended up modifying the push/pull kit extensively, but it's a good starting point and saved me a lot of time vs building everything from scratch. Great service from Summit, as always...I was able to return the incorrect unit and replace it with correct unit. Thank you Summit and Moroso. ...read more
