Hi Guys,

I've got my battery mounted in the boot and have seen the battery isolation solenoids such as the painless kit (but seem to be unable to source locally). Also seen the Datsport battery box Kit that includes some isolation function

Also haven't been able to find a wiring diagram on how to wire something homegrown up either.

I'd like to have something like the painless kit where you can have a switch in the cabin that cuts off the battery in the boot with the solenoid doing the cutoff mounted in the boot next to the battery

Any ideas?

Swanny

Shooting from the hip a little bit here - one of my mates is right into his 4WDing, and was showing me the solenoids that some of the serious (christ they are heavy..) winches use. Might be worth asking at a 4WD specialist, and seeing what sort of currents they can move.

Thanks Bob, heaps of info on the web covering the 4wding scene just can't find anything for what I'm trying to achieve.

Am I just been paranoid? been driving a car with a battery in the boot for years but I'd like to set this one up with that extra bit of safety

I am thinking about something like this, 200A continuous rated and it looks like 1400A for 10 sec. I think it would be easier to do with one of the ones where you need one solenoid to drive the winch forward and one solenoid to drive it in reverse though, I think (I am using that word a bit much) they are more like a SPDT relay, which is basically what you are after.

On the safety front, not sure of your purpose for the isolation (i.e anti-theft, motorsport, etc), but if you want the isolation to stop the electrics when the car's running, don't forget to run your alternator output wire through the isolation system (switch/solenoid/whatever).

my relo's are simple

cut +ve terminal post holder and crimp on large ring terminal
put that onto kill switch
from switch to cable that runs to boot
into another kill switch from that to cable and onto a post holder
run a ground wire to body of car
double check u still have a ground for engine

heres a lil more detail and some pics as i havent done one for ages
but will do a write up in the next month or so when i do this for the 200b

oh also before you ask, killswitch in engine bay is VERY handy and having one next to bat helps too

Speak to Baz at Datsport - He helped me set up my Ford Starter solenoid (supercheap autos) mounted next to my battery with relay and fuse so that if there is any type of short or if someone tries to hot wire car then fuse is blown and no power through car at all!!!

Works a treat

Happy to do a diagram if required.

Hi Marko

Bit late on the reply but that would be great if you could knock up a wiring diagram

Thanks

Swanny

Seems like another DIY kit is needed.
BTW we use a golf buggy solenoid.
Super reliable as they are rated for continuous use.
the way we wire them up its fully automatic protection.

Hi mate, just saw your reply!

Will knock up a diagram tomorrow if thats cool?

Could you maybe do a small write up on (with diagram) so a mod can put it in the tutorial section?

As requested here is a brief description on how to install a remote starter solenoid and battery relocation set up.

Please note this is based on a new wiring install that I completed when fitting and SR20 but can be adapted to suit a relocation of battery if using an existing loom and standard or alternative engine package.

1.Securely fix battery in battery box in boot - be sure to fix battery hold down to body securely - plenty of threads on this.

2. Purchase a Ford Remote Starter Solenoid (or similar) - sourced from local Supercheap store. Fit this in the boot close to the battery - I placed mine on the rear left shock tower support bracket.

3. Run a large cable from battery +ve terminal to the input on the remote starter solenoid.

4. Run a large cable from the output on the remote starter solenoid through the cabin to the starter motor. This connects to the existing power connection lug on the starter motor.

5. Add another large gauge cable from the starter lug to the large lug on the alternator.

6. If new wiring is being installed then run a cable from the "Start" side of the ignition switch (or use existing cable if being retained) to the main starter motor solenoid.

7. Splice another wire off this cable and run it through the cabin to a relay located in the boot (close to the remote starter solenoid).

8. Wire up the relay as per normal relay wiring - constant battery power (30), earth (85), ignition switch power in (86) and output to the remote starter solenoid (87). Let me know if you get stuck with this part!!

9. It is also suggested that an 80 amp Maxi Fuse be fitted between the input and outputs of the remote starter solenoid. This allows charge from alternator to bypass the solenoid but will blow if the cable is damaged, shorts out etc - this is an important safety mechanism - Thanks Baz!!!

10. All thats left to finish this setup off is to connect the sense and charge light cables from the alternator. If using existing wiring loom than this can remain intact. Let me know if you need further hep with this part as each set up will vary depending on existing wiring, engine package etc.

Please PM me if you need any further help!

Here is a diagram that should make the above a little clearer:

To add to the above
if a switch is added to the relay wire that is spliced to the starter solenoid.
this will ensure that if your car is hot wired & the starter terminals jumped
the relay will not activate and the starter current draw will blow the maxi fuse.

ALL power will then be lost & confuse the sh*t out of the thieves
Just make sure you carry a spare fuse.

Thanks for that Baz, I know we discussed this but I couldn't remeber the setup configuration!

looks like a Ford starter Relay used in link below(beware if Chinese clones)
heres a kit w/o the relay but a drawing for it. Make your own
