Piranha DBS150 Mk111 dual battery

Pat, doesn't the unit have engraved or embossed numbers, like on relays?

Some of those numbers are quite common.

Maybe try a auto sparkey, he would be able to find out.

Buy a decent unit first up instead of fitting something now and replacing it later.
Redarc Solenoid Battery Isolator Only decent worthwhile battery isolator for 12v
I would not fit that Piranha as a decoration on my kids bike - if I had a kids bike.

Pat,
I assume you mean the actual power lead to each battery??

There should be;
1 x black wire, it goes to 'earth'
1 x red wire, it is recomended to go to "wiper motor circuit" as it's 12v source (or ignition switch)
and the 2 thick red/orange battery leads, one goes to each respective positive (+) battery terminal...

The red/orrange battery leads should have the words "MAIN" battery on one and "AUXILLIARY" battery on the other... ???

so simple.... and is GUARANTEED in writing to work with Deep cycle and also Cranking batteries unlike cheap bi-metal solinoids... couldn't help it 0zi... LoL

Good on the people saying they arebleep.
Ive been running mine a year and a half, no fail yet. Im happy you paid 3 times the price i got mine for- Ill be sure to think of you if I have to buy another 2 and still have spent less than you did.

You need an education in etiquette pal.

Almost all your replies on this forum carry such an obnoxious and "superior" tone that nobody is going to take any notice of your advice, regardless of its true technical merit.

Pat,
To answer your question Mate.

Just had a look at at mine (DBS150 Mk11) and looking at the front of the unit, the left hand heavy duty wire goes to the Primary battery and the right hand heavy duty wire to the Auxilliary Battery.

In operation, the unit will allow the Primary battery to receive its full charge first, then cut over to charge the Auxilliary one. Indication of this occuring is by a green indicator light on the unit showing the Auxilliary is being charged.

The only difference between the Mk11 (mine) and Mk111 (yours) is that the Mk111 provides a facility to connect an external (eg. in cabin) meter to monitor both batteries. (I think) TJM, as a Piranha distributor will be able to confirm this if you wish and they stock the meters, should you want one.

Despite other comments in this post Pat, the Piranha product is recognised by many Auto Elecricians to be a quality product.

Have a good one!

Hi. Forget all about thos Pirahna, Arrid twincharge type things. All you need is a good quality solinoid and good sized cabling. All those fancy named things are only solinoids rearly and they cost a bomb for what they do. I have been running a DSB on the drawbar of my carava for some while now and only use an ignition activated 180amp soliniod
