When A/C On high my led blinkers stop blinking

Hi everyone,
I have led bulbs for my tail lights, brake lights, and all blinkers. The sockets are all stock. I installed the 2 new realys reguired for the blinkers and the hazards. They work great but when I run my A/C on hight fan the blinkers stop working. Its wierd. Turn off the A/C the blinkers come back on. Any thoughts? Help!!!! Thx Scott....

It could be alternator is not outputting enough current/power in operating all selected accessories.
Increase engine rpm and all work?
With A/C, you should have a min of 61/63 AMP alternator.

Thumbs up Re: When A/C On high my led blinkers stop blinking

Yep that was it! After I posted the question I went out and started my car and yep just 1000 rpm more it fixed the problem. Ordered a Powermaster Alternater 100 amp and harness adapter kit. Thx very much for the fast response! Scott

Btw would the 100 amp alternator ruin my amp meter? Do I have to install the American Wire 12 volt factory style meter? Thx Scott

OE ammeter should be fine as its 'monitoring' points are the horn relay buss bar and battery junction block.
The ammeter measures the loss of voltage about the length of red wire between these two points.

Re: When A/C On high my led blinkers stop blinking

You may want to do some voltage drop tests to see if you have any excessive drops through things like the bulkhead connector, ignition switch, and so on.

As far as going with the larger alternator it probably will have a higher output at a lower RPM than your old one which could take car of your issue but keep in mind that right now, let's say you have an 63A alternator on the car, this should be fine as it was made to keep up with a less than 63A current draw from your electrical system. If later you do upgrade to a 100A alternator and the electrical draw is still under 63A, then all is good BUT if later you start adding more electrical items to the car and now the draw is getting into the 90A area the original wiring may needs some upgrades as it was only designed for so much.
