HID Problem on 80 Series

Ok, one for the gurus.....
Mates 80 series cruiser had standard headlights, led light bar and 4x light force halogen spotties. Everything worked perfectly and has done so for a while.
He has upgraded and now has HID low and high beams, led light bar and 2x light force factory HID spotties.
For some reason, the led bar and the hid spotties won't both energise at the same time unless he is revving just above idle. Sometimes at idle both will illuminate but only after the redarc brings the second battery online. The primary battery appears fine, kicks over the 6 cylinder diesel with no dramas.
If the both are turned off at their respective switches, the first one to be turned on when hi beam is on remains on and turning the other one on will do nothing, doesn't make a difference which is on first, it will be the only one to come on.
Any thoughts?
Thanks
Tim

There is a voltage-drop problem. Probably some under-size wiring. Can be located easily with a voltmeter.
After the first one comes on the voltage drop prevents the second from firing up.

Yep, What Allan Said.

It would also be helpful to know the power rating of all of the lights.

Could also be the first battery or alternator.

Measure and read the voltage at the lights and at the battery while lights are off and on.

It could also be a tricky thing such as a poor earth connection of the relays. The first relay pulls in OK but then raises the 0v on the common connection preventing the second from pulling-in. Once again, voltage testing would reveal the problem but you do need to know how to troubleshoot in a logical and sequential manner......... or be lucky!

That's Jesus protecting the rest of us from his backyard hid upgrade. Thank a Mick for that.

Me too! I wish people would stop installing illegal lighting.

Lol..well said above.

"Mates 80 series cruiser had standard headlights, led light bar and 4x light force halogen spotties.............He has upgraded and now has HID low and high beams, led light bar and 2x light force factory HID spotties."

Maybe he should go to spec savers..?

Upgraded to overkill, by the sounds of it. :-)

We had an 80 series, and I fitted HID inserts to the inner hi-beam headlights only. Was so good I took the driving lights off it.

Yeah, think Specsavers have a "2 for 1" deal going at the moment.

It sounds like the bloke with the 80 series (and could it actually be the OP?) loves searing the retinas out of the drivers of those oncoming cars 3kms away, who are .01 second too slow in dipping their headlights.
I have an older brother who had a 60 series 'Cruiser fitted with two monstrous Cibies back in the late 1980's.
He loved to blitz oncoming cars who had badly adjusted lights, or who were too slow to dip their lights.
So .. one night he light-blitzes this oncoming bloke, who he reckoned had dazzling lights.
The oncoming bloke promptly turned on a light show that would make a set of WW2 searchlights look like candles!
The other blokes lights were so bright, the brother had to pull up - he couldn't see anything!
This other bloke had about 6 spotties, in total!
So, just remember, no matter how smart you think you are, someone will eventually give you your come-uppance!

Yes Ron, and people should also realise that if you blind the oncoming bloke, either intentionally or not, you may cause him to provide you with a head-on collision!

Bonz, that's right! - and I reckon if you met this bloke with the 80 series, with all his lights on, on the highway at night, you'd be calling out his full name, too!

HID lights need a large amp draw to strike and draw down even a big battery momentarily..

Even with a direct harness from the battery, my Range Rover Classic used to give a low voltage warning on an accessory volt meter that I had immediately the lights were turned on.

One they are on there is no problem but it is the energising of the HID transformer that causes the problem.
So don't turn all the lights on at once.

Appart from the HID headlight upgrade being illegal ........ There are some issues with the way headlights in toyotas are wired ...... they supply positive to the common of the headlight lamps and switch the appropriate filement to earth
This causes no end of confusion.
Depending on how the spotloghts have been wired ... introducing an electronic headlight system can cause the spotties to fale or becaome flakey.

betya if ya put standard halogen lamsp bak the problems go away.

Yeh until the low beam filament blows then the spotties wont work.

Thanks for the feedback we have found the problem and Al was right.
The original loom voltage drops and it is insufficient to bring both relays in for the light bar and the hid spotties. Might have to look at upgrading the loom.
In answer to the questions and comments,
-not my 80 series, I have a 150....
-illegal? Well yeah the low beams are, are we all saints here? Please.
-bright? Wow, unbelievable, from candles to search lights, the improvement is phenomenal . Doesn't need spec savers, needs oxy goggles! Would def consider it for high beam upgrades in our smaller car, I think they were about $90 for H4 globe replacements at jaycar.

Does he drive around with his foglights on all the time too?

The low beam HIDs are illegal and very irritating.
